SDI Input and SDO Output
The SDI input connector (J1) is a 75Ω BNC connector. The SDI input should conform to the SMPTE 424M,
SMPTE 292M, or SMPTE 259M standards.
The SDO output connectors (J2 and J3) are 50Ω SMA connectors. When using only one side of the output pair,
the other side should be terminated with a 50Ω SMA termination. For example, when only using the SDO output,
¯¯¯¯
SDO should be terminated with a 50Ω SMA termination.
DC Power Connectors
The VCC and GND power connectors should be powered with a DC input voltage of 3.3V ± 5% (3.6V maximum).

SPI Mode / Pin Mode Select (JP1 – JP4)
JP1, JP2, JP3, and JP4 are used to select between SPI Mode or Pin mode. To select Pin Mode, set four jumpers
as shown in Figure 2, and to select SPI Mode, set four jumpers as shown in Figure 3. Either Pin Mode or SPI
mode must be selected for proper operation; do not leave JP1-JP4 open.
Figure 2. Pin Mode Select
Figure 3. SPI Mode Select
MUTEREF (JP5)
JP5 allows control of the MUTEREF function and may be used in either Pin Mode or SPI Mode. MUTEREF is an input
voltage used to set the threshold for ¯¯¯
CD . The MUTEREF DC input voltage should be between 0V and 3.3V. Refer
to the LMH0384 datasheet for details. Leave JP5 unconnected for normal operation.
Pin Mode Controls (JP6 – JP8)
JP6, JP7, and JP8 are used to control LMH0384 features while the device is configured for Pin Mode. Jumpers
should not be placed on JP6, JP7, or JP8 while the device is configured for SPI Mode.
¯¯¯
CD and MUTE (JP6)
¯¯¯ ) monitoring and MUTE control. ¯¯¯
JP6 allows Carrier Detect (CD
CD is high when no input signal is present. MUTE
may be used to force the outputs on or off, or tied to ¯¯¯
CD to allow automatic mute operation based on the input
signal. To activate mute and force the outputs into a muted condition, set the jumper to pull MUTE to VCC. To turn
off mute so that the outputs will never mute, set the jumper to tie MUTE to GND. For normal operation, set the
jumper to tie ¯¯¯
CD to MUTE for automatic mute control. The LMH0384 MUTE pin has an internal pulldown (to
disable mute), so JP6 may be left unconnected and the LMH0384 will never mute.
BYPASS (JP7)
JP7 allows control of the equalization BYPASS function. To put the device into bypass mode, set the jumper to pull
BYPASS to VCC. To turn off bypass (for normal operation) set the jumper to pull BYPASS to GND. The LMH0384
BYPASS pin has an internal pulldown (to disable bypass), so JP7 may be left unconnected for normal operation.
AUTO SLEEP (JP8)
JP8 allows control of the AUTO SLEEP function. To put the device into auto sleep mode in which it will power
down when no input is detected, set the jumper to pull AUTO SLEEP to VCC. To turn off auto sleep and prevent
the LMH0384 from automatically powering down, set the jumper to pull AUTO SLEEP to GND. The LMH0384
AUTO SLEEP pin has an internal pullup (to enable auto sleep), so JP8 may be left unconnected to enable auto
sleep mode.

SPI Header (JP9)
JP9 is the SPI (Serial Peripheral Interface) header. It allows access to the SPI pins (¯¯¯
SS , MISO, MOSI, and SCK)
while the LMH0384 is in SPI mode. To use the SPI interactive GUI, plug the 6-pin parallel cable between this
header and JP7 on the SPA dongle to connect the pins one-for-one as shown in Table 1. The SPA dongle requires
special software and must be connected to the PC via the USB – see the Software Setup section.

SPA Dongle Description
The SPA dongle is required to use the SPI interactive GUI. The SPA dongle connects between the LMH0384 SPI
pins and the USB input of a PC. The SPA dongle is shown in Figure 4. JP7 is the SPI Header. The SPA dongle is
powered through the USB, and the D1 LED is RED when the SPA dongle is connected to a PC via the USB to
indicate the board is powered.

Output Swing
The Output Swing control shows the current value of the LMH0384 output amplitude
and allows adjustment in 100 mV increments from 400 mVP-P to 800 mVP-P. The
default setting is 700 mVP-P. The Output Swing may be set either by clicking on the “+”
or “-” buttons, or by grabbing and spinning the “handle” on the knob for a quick
adjustment.
Output Offset
The Output Offset control shows the current value of the LMH0384 output common
mode voltage and allows adjustment in 200 mV increments from 1.05V to 1.85V. At
the “Max” setting, the outputs are referenced to the positive supply and the output
common mode is 2.1V. The default setting is 1.25V. The Output Offset may be set
either by clicking on the “+” or “-” buttons, or by grabbing and spinning the “handle” on
the knob for a quick adjustment.
Cable Length
The Cable Length shows the interpreted Belden 1694A cable length of the CLI register,
both with a visual bar graph and a decimal readout. The Cable Length is only valid when
an input signal is detected, and is greyed out when there is no input to the LMH0384.

Input Launch Level Control
The Input Launch Level Control is useful to compensate for attenuation
of the input signal prior to the equalizer due to a passive splitter or nonideal input termination network.
The Coarse Amplitude control shows the current setting of the Coarse
Control register and may be used to set the input for either 0 dB (default)
or 6 dB of input attenuation. At the default setting of 0 dB, the LMH0384
operates normally and expects a launch amplitude of 800 mVP-P. With
the Coarse Amplitude set to -6 dB, the LMH0384 is optimized for input
signals with 6 dB of input attenuation (400 mVP-P).
The Launch Amplitude Fine Tuning may be used to further fine tune the
LMH0384 input compensation, from -2.2 dB to 2.9 dB. The Launch
Amplitude Fine Tuning may be set either by clicking on the “+” or “-”
buttons, or by grabbing and spinning the “handle” on the knob for a quick
adjustment.
Sleep State and Signal Detect
The Sleep State control shows the status of the Sleep Mode register bits and
allows control over the sleep mode. The Sleep State settings are as follows:
On: Force the LMH0384 into sleep mode (powered down) regardless of whether
there is an input signal or not.
Off: Disable sleep mode (force LMH0384 to stay enabled).
Auto: Sleep mode active when no input signal detected (default mode).
The LMH0384 Sleep State indicator shows the current status of the LMH0384 sleep state. It is GREEN to indicate
sleeping or OFF to indicate not sleeping.
The Signal Detect shows the status of the input carrier detect. It is GREEN to indicate the input signal is present or
OFF to indicate the input signal is absent.
Output Mute and Equalizer Bypass
The Output Mute indicator shows the mute status, and the button may be used to toggle the mute
function. The indicator is GREEN to indicate mute (LMH0384 outputs are muted) and OFF to
indicate normal mode (outputs are not muted).
The Equalizer Bypass indicator shows the bypass status, and the button may be used to toggle
the bypass function. The indicator is GREEN to indicate bypass is active (equalization is
bypassed) and OFF to indicate normal mode.
Extended 3G Reach Mode
The Extended 3G Reach Mode indicator shows the status of the Extended 3G Reach
Mode register bit, and the button may be used to toggle this register bit. The indicator is
GREEN when the bit is set for extended 3G reach mode, and OFF when the LMH0384 is
set for normal mode. Note that the indicator shows the status of the register bit – not
whether the device is actually in extended 3G reach mode or not. If extended 3G reach
mode is set, the LMH0384 will remain in this mode until the input cable is physically changed or power is cycled.
For example, extended 3G reach mode is forced, and then it is turned off. The indicator will show it is off, but the
SD384SPI EVK User Guide
Rev 1.1

LMH0384 will still be in extended 3G reach mode until the input cable is changed or the device power is cycled.
The GUI provides a simple way to reset the extended 3G reach mode: the Extended 3G Reach Mode Reset button.
This button will reset the equalizer, and is similar to removing and re-applying the input cable.
Application of CLI: Extending 3G Reach
This control may be used to enable a “Smart 3G Reach Mode” to extend the
LMH0384 3G reach by up to 15m while still maintaining the performance at HD and
SD data rates. When this mode is active, it automatically controls the extended 3G
reach mode and only enables extended 3G reach mode when the input cable length
to the equalizer is less than the threshold. The indicator is GREEN when this mode
is active, and OFF when this mode is not used (default). When this mode is active,
the “Smart 3G Reach Mode Threshold” may also be changed. The default threshold
is 180m (Belden 1694A), which means that extended 3G reach mode will only be
active when the input cable length is <180m. When the input cable length is ≥180m, extended 3G reach mode will
automatically turn off, allowing equalization of much longer cable lengths for HD and SD data rates. When Smart
3G Reach Mode is active, the Extended 3G Reach Mode control cannot be used (since it is controlled
automatically). Refer to the LMH0384 datasheet for details.
Registers Tab
The Registers tab displays all registers for the LMH0384. Figure 8 shows the Registers tab. The Value field
indicates the value of the currently selected register.
Figure 8. LMH0384 Registers Tab
Each register can be examined in detail by either double clicking on the desired registers fold bar (with the address
and the register name, e.g. 0x00 – General Control) or by single clicking the icon at the right of the fold bar (two
inverted carats).
The Refresh button will re-read the currently selected register and the Refresh All will read all registers in the
device. Changes may be made to the registers by checking or un-checking the individual register bits or typing in a
new register value in the Value field. After setting the appropriate register value, the Apply button must be pressed
to apply the changes. The detailed view of the General Control register is shown in Figure 9 with Verbose
Descriptions checked and Figure 10 with Verbose Descriptions un-checked.

Trouble Shooting
If the following window (Figure 14) opens after starting the ALP software, double check the hardware setup.
Figure 14. Analog LaunchPAD No Devices Error
It may also be that the USB driver is not installed. Check the device manager. There should be an ”NSC ALP
Nano Atmel” device under the “Universal Serial Bus Controllers” as shown in Figure 15.
Figure 15. Windows XP, Analog LaunchPAD USB Driver
The software should start with only “LMH0384 - Nano” in the “Devices” pull down menu. If there are more devices
then the software is most likely in demo mode. When the ALP is operating in demo mode there is a “(Demo Mode)”
indication in the lower left of the application status bar as shown in Figure 16.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
