EQ_DISABLE Digital Input. Equalizer Disable.

0: Normal Operation

1: Disables the equalizer to allow for insertion of upstream data onto the signal path, e.g. RS-485.

This pin must be asserted high or low. Do not float this pin.

COLOR Digital I/O. Color Indicator/Override.

0: Monochrome

1: Color

When used as an output, this pin indicates whether the incoming signal does or does not have a colorburst. When

used as an input, this pin forces the state machine to into monochrome or color mode. See Figure 49 and associated

text for more information on functionality.

When COLOR is not externally driven, it is an output pin with a 13k (typical) output impedance. It is capable of driving

5V, high-impedance CMOS logic.

Note: The COLOR indicator may be invalid for monochrome signals over greater than ~4800 feet. The device will still equalize properly if this occurs.

INVERT Digital I/O. Polarity Indicator/Override.

0: Nominal Polarity.

1: Inverted Polarity.

When used as an output, this pin indicates the polarity of the incoming signal. When used as an input, this pin

controls whether or not the input signal is inverted in the signal chain. See Figure 48 and associated text for more

information on functionality.

When INVERT is not externally driven, it is an output pin with a 13k (typical) output impedance. It is capable of driving

5V, high-impedance CMOS logic.

In stand-alone mode, toggling this pin high-low-high or low-high-low will make the equalizer reacquire the signal.

Digital Output.

0: Signal is not equalized (or not present).

1: Signal is equalized and settled.

Note: The LOCKED indicator may be invalid for monochrome signals over greater than ~4800 feet. The device will still equalize properly if this occurs.

Digital Input. Freezes equalizer in its current EQ state.

0: Continuous Update

1: Freeze EQ in current state.

For stand-alone operations, connect FREEZE to the LOCKED pin to enter the recommended Lock Until Reset mode.

Functional Description

MegaQ™ Overview

MegaQ™ is a fully automated, stand-alone equalizer for composite video transmitted over UTP (Unshielded Twisted Pair, i.e. Cat 5, Cat 6, etc.) or coaxial (RG-59) cables.

Differential video signals sent over long distances of twisted pair wire exhibit large high frequency attenuation, resulting in loss of high frequency detail/blurring. The exact loss characteristic is a complex function of wire gauge, length, composition, and coupling to adjacent conductors.

The video signal can be restored by applying a filter with the exact inverse transfer function to the far end signal. MegaQ™ is designed to compensate for the losses due to long cables, and incorporates the functionality and flexibility to match a wide variety of cable types and loss characteristics.

While MegaQ™ was designed and optimized for stand-alone operation, with no need for any external control of any kind, it has an optional SPI serial interface with some additional features.

See “Additional Equalization Modes Available With the Serial

Interface” on page 22 for more information on the features and

operation of the serial interface.

Application Information

Unshielded Twisted Pair (UTP) App Circuit

Figure 45 shows the complete schematic for a MegaQ™

equalizer configured for unshielded twisted pair (UTP) cable. The input signal is terminated into the network formed by R1, R2, and R3. C1 and C2 AC-couple the signal into MegaQ™. To protect the front-end circuitry, 5V transorbs (Z1 and Z2) should be used instead of diodes because the signals on either differential input may swing far enough below ground to turn on a diode and distort the video.

On the output side, C5, R5, and C4 form a compensation network, while R6 provides 75Ω source-termination for the video output. MegaQ™ has an native gain of 6dB, so when VIDEO OUT is terminated into 75Ω (the input to a DVR, TV, etc.), R6 and the

75Ω terminator form a 2:1 divider, producing standard video amplitude across the 75Ω terminator.

Coax Input Circuit

Figure 46 shows the input termination recommended for coaxial

cables. The differential termination resistance is now 75Ω to match the characteristic impedance of the RG-59 coax cable. C3 bypasses high-frequency noise on the coax ground line to system ground. This allows the coax ground to be independent of the system at low frequencies (DC to 50/60Hz) to accommodate differences in the ground potential of the remote video source(s).

The coax startup network (D1, R4, C4) prevents a rare start-up condition that can occur when a high average-picture-level (e.g. white screen) video signal is present on the inputs before the power has been applied.

FIGURE 46. APPLICATION CIRCUIT FOR COAX CABLE

Dual UTP/Coax Input Circuit

If desired, it is also possible to support both UTP and coax cables with the same PCB layout using two SPST switches that are closed when in coax mode (Figure 47). Since UTP requires a

100Ω termination network while coax requires 75Ω, a switch to introduce a shunt 300Ω resistor when in coax mode will change the termination from 100Ω to 75Ω. A second switch is required to engage C3. The addition of the coax startup circuit (D1, R4,

C4) can unbalance the capacitance of the differential pair and degrade the CMRR in UTP applications. This in turn could cause excess noise at long lengths of UTP. In UTP applications, if the output signal is too noisy at long distances, an optional capacitor

Cx may be used to balance the capacitance of the differential inputs. The value of Cx should be determined by calculating how much trace capacitance is added by the coax startup circuit. A typical value for a good layout is ~5pF. Note that only coax or UTP should be connected at any one time - this circuit does not multiplex between them.

FIGURE 47. APPLICATION CIRCUIT FOR UTP/COAX CABLE

Input Multiplexing

Placing a semiconductor multiplexer in front of this part may increase high frequency attenuation and noise. However a low-capacitance mechanical relay may be acceptable. Note that changing from one channel to another in Lock Until Reset mode will require a reset (INVERT toggle) to trigger equalization of the

new channel (see “Lock Until RESET” on page 21).

For best performance, do not multiplex the inputs to the equalizer - this can further degrade the signal. Instead, multiplex at the output after equalization has been performed.

Stand-Alone Operation and Configuration

In its default stand-alone configuration, MegaQ™ features two modes of automatic cable equalization: Lock Until Reset and

Continuous Update. Lock Until Reset is the recommended mode for most applications.

LOCK UNTIL RESET

In the Lock Until Reset mode, once MegaQ™ finds the optimum equalization and the LOCKED signal goes high, the equalization is frozen and will not change until either the power is cycled or the INVERT signal is toggled, which initiates a re-equalization of the input signal. Re-equalization is usually only necessary during device/system evaluation - in normal operation MegaQ™ powers-up, acquires and equalizes the signal, and continues to equalize until/unless it is powered-down. If the signal is lost in

Lock Until Reset mode, the LOCKED pin will not go low until/unless the device is reset by toggling the INVERT pin. A reset should only be necessary if the length or type of cable was changed without cycling power.

To enable the Lock Until Reset mode, tie the LOCKED output pin

to the FREEZE input pin as shown in Figure 45 on page 20.

To generate a reset (and trigger a re-equalization), toggle the external INVERT pin to its opposite state for at least 1ms.

Depending on the initial state of INVERT, this would be a high-low-high or low-high-low sequence.

CONTINUOUS UPDATE

In the Continuous Update mode, MegaQ™ will continuously try to find the optimum equalization solution. When the equalization has settled for 100 sequential video lines with no changes, the

LOCKED pin will go high. However once lock is achieved, noise and average-picture-level changes may cause the device to unlock, causing some image perturbation while MegaQ™ re-equalizes.

The Continuous Update mode is enabled whenever the FREEZE pin is set to a logic low (grounded).

Polarity Detection and Correction

MegaQ™ features polarity detection and correction, automatically detecting incorrectly-wired input signals and inverting the signal inside the IC as necessary. The detected polarity is indicated by the state of the INVERT pin.

The INVERT pin has 2 modes of operation. It is typically used to indicate whether or not the incoming signal is inverted (the “+” signal on the “-” input and vice-versa). The state of the invert signal is then used to tell the signal processing logic whether or not to invert the signal in the signal path.

A logic high on INVERT indicates that the positive differential input signal is on IN- (pin 5) and the negative differential input signal is on IN+ (pin 3). A logic low indicates nominal polarity.

However the unique design of the INVERT I/O pin (Figure 48) also

allows MegaQ™’s internal inversion detector to be overdriven externally, forcing MegaQ™ to invert or not invert the signal regardless of the state of the inversion detection function. This is not necessary in normal operation, but it may improve performance in particularly noisy environments when the polarity of the signal is guaranteed to be correct.

The COLOR Pin

The color pin has 2 modes of operation. It is typically used to indicate whether or not the incoming signal has a colorburst or not. The state of the color signal is then used to tell the signal processing logic whether or not it can rely on the presence of a colorburst signal. A logic high indicates a color signal; a logic low indicates monochrome.

However the unique design of the COLOR I/O pin (Figure 49) also

allows MegaQ™’s internal color detector to be overdriven externally. This is not necessary in normal operation, but it may improve performance in particularly noisy environments when the signal type is predetermined.

Monochrome Video Signals

MegaQ™ will equalize monochrome signals to the same distance as color signals. However due to the high level of noise past

~4800 feet, the COLOR and LOCKED indicators may become invalid for monochrome signals. The device will still equalize properly if this occurs.

Security Cameras

MegaQ™ is ideal for security camera installations.

The automatic adaptive equalizer doesn't need any active silicon on the transmit side of the cable, enabling upgrading of older installations without having to touch the installed camera base, including older monochrome cameras.

MegaQ™ automatically adjusts for wiring polarity errors as well as adjusts for optimum image quality. These features eliminates the need for the installer to make any adjustments.

With an extended equalization range of 5300ft, the ISL59605 enables cameras to be placed in even more remote locations, enabling coverage of up to three square miles from a single monitoring station.

Additional Equalization Modes Available

With the Serial Interface

In addition to the Lock Until Reset and Continuous Update modes, software control of MegaQ™ through the SPI interface adds a Lock Until Signal Loss mode and a Manual Equalization mode.

Note: When controlling MegaQ™ through the SPI interface, the

external FREEZE pin must be tied to ground (logic low). Failure to keep FREEZE at a logic low will prevent the software controls from working properly.

All of the equalization modes are selected via the two “Locking

Mode/Manual Length Enable” register bits, 0x05[1:0].

CONTINUOUS UPDATE

Continuous Update mode is entered by setting address

0x05[1:0] = 00b. Continuous Update behavior is the same as described in the stand-alone mode.

LOCK UNTIL RESET

Lock Until Reset mode is entered by setting address

0x05[1:0] = 10b. Lock Until Reset behavior is the same as described in the stand-alone mode, with the exception of how to generate a reset.

To generate a reset via software, select Continuous Update mode and then return to Lock Until Reset mode (register 0x05[1:0] =

00b then 10b). Toggling INVERT (either the hardware pin or the software bit) will not cause a reset/re-equalization event.

LOCK UNTIL SIGNAL LOSS

Lock Until Signal Loss mode is entered by setting address

0x05[1:0] = 01b. Lock Until Signal Loss can only be enabled via the SPI interface.

In the Lock Until Signal Loss mode, MegaQ™ will freeze the equalization once the LOCKED pin goes high (in the same way as

Lock Until Reset). Unlike the “Settled” state in the Continuous

Update mode, only a signal loss lasting more than 1ms (typical) will cause MegaQ™ to re-equalize the signal when it returns. In this sense, the Lock Until Signal Loss mode can be considered as halfway between the Continuous Update mode and the Lock Until

Reset mode. The Lock Until Signal Loss mode is useful, for example, when testing or demonstrating a system by plugging in multiple different length cables - it eliminates the need to also generate a reset. To prevent potentially undesired re-equalization, signal losses lasting less than 1ms (typical) do not trigger a re-equalization.

MANUAL LENGTH

Manual Length mode is entered by setting address

0x05[1:0] = 11b. Manual Length mode allows the forcing of specific cable lengths, cable type, DC gains, etc. (see the Register

Listing on the next page). The “Cable Type” bit (0x05 [4]) allows selection between the two most common cable types for security video: Cat 5/6 or steel core RG-59 coaxial. However since many of MegaQ™’s automatic functions and adjustments are disabled in Manual Length mode, performance is almost always worse than what is achieved in any of the automatic modes. For example, automatic polarity correction is disabled so the polarity must be manually set using the INVERT bit. There is no practical reason to ever use Manual Length mode in normal operation.

Serial Interface Protocol

While MegaQ™ is designed to work as a stand-alone equalizer, it does have a serial interface that can be used to control it and monitor its state.

The serial interface is used to read and write the configuration registers. It uses three signals (SCK, SD, and SEN) for programming. The serial clock can operate up to 5MHz

(5Mbits/s). The “Serial Timing Diagram” on page 8 shows the timing of serial I/O.

A transaction begins when the host microcontroller takes SEN

(serial enable) high. The first 8 bits on the SD (serial data) pin are latched by MegaQ™ on the rising edge of SCK (serial clock) to form the address byte. The MSB of the address byte indicates whether the operation is a read (1) or a write (0), and the next seven bits indicate which register is to be read from or written to.

Each read and write operation consists of 16 bits: 8 bits for an

address byte followed by 8 bits of data. See the “Serial Timing

Diagram” on page 8 for more details on using the SPI interface.

TABLE 2. ADDRESS BYTE FORMAT

A6 A5 A4 A3 A2 A1 A0 0 = Write

1 = Read

(MSB) (LSB)

WRITE OPERATION

After the address byte is clocked in, the next 8 bits should contain the data to be sent to the register identified in the address byte.

READ OPERATION

After the rising edge of the 8th clock after the address byte is clocked in, the microcontroller should tristate the SD line so MegaQ™ can begin to output data on the SD pin (from the register identified in the address byte), beginning on the 9th rising edge of SCK. The data should be latched on the falling edge of SCK to allow enough time for the data to

settle. See ““Serial Timing Diagram” on page 8 for more details on how

to read from the registers.

Bypassing and Layout

Considerations

MegaQ™ requires a dedicated ground plane in order to function properly. For 2-layer boards, pour a quarter-inch ground plane extending around the device on both the top and bottom layers.

Ensure that the ground plane on the bottom layer is a solid plane with no traces cutting through it. Bypass capacitors must be placed as close as possible to the device in order to ensure good performance at longer lengths of equalization. Ensure that the ground connections for the bypass capacitors connect directly to the same uniform ground plane described previously.

General PowerPAD Design Considerations

The thermal pad must be connected to the ground plane for heat

dissipation. Figure 50 is an example of how to use vias to remove

heat from the IC.

FIGURE 50. PCB VIA PATTERN

The thermal pad is electrically connected to GND through the high resistance IC substrate. We recommend you fill the thermal pad area with vias. The via array should be centered in the thermal pad and placed such that the center on center spacing is

3x the via radius. Vias should be small, but large enough to allow solder wicking during reflow. Connect all vias to ground. It is important the vias have a low thermal resistance for efficient heat transfer. Do not use “thermal relief” patterns. It is important to have a solid connection of the plated-through hole to each plane.
