4.1.4 Video Decoder
The FLI8532 chip has a sophisticated Analog Front End with 16 reconfigurable inputs through an analog multiplexer to anti-alias filters before the Analog to Digital Converters
(ADCs). These integrated features eliminate the need for any devices between the input connector and the pin of the FLI8532.
The figure above depicts the data-path for the AFE and Decoder blocks with connections to the input multiplexer that selects whether the data follows the Main Video Channel or PIP video channel.
The analog front end of FLI8532 provides the capability to capture 16 analog video inputs which can be a combination of Composite (CVBS), S-Video (SY, SC), YPrPb (Y, Pr, Pb) or
RGB (R, G, B).
The FLI8532 front end provides filtering capability depending on the type of input video signal in use. The use of these filters eliminates the need to have any external filter components.
The filters included are both in the analog as well as digital domain. The digital filter eases the design requirement of the analog anti-aliasing filter.
The analog filter is implemented with the following 3dB cutoff definition.
10 MHz – for SDTV
20 MHz – for 480p/576p
40 MHz – for 720p/1080i
180 MHz – for Graphics
The digital filters are implemented as Quarter Band (QB), for SDTV and 480p/576p and as Half
Band (HB), for 720p/1080i modes.

4.2 Power Supply Circuit Description
The power supply provides DC electrical power to all the electrical components in the rear projection television.
DVR-4240 also contains Ballast that provides high voltage 380V necessary to strike the lamp when the rear projection television is powered up. The attached fan draws cooling air through the power supply, as well as through the rest of the rear projection television.
4.2.1 Location diagram of power board
The power supply consists of the EMI filter, PFC, Standby power, and Main power. The system required voltage is converted from the Standby and Main power, and the high voltage DC 380V from PFC is applied to the lamp and Main power.
Line voltage can directly input from 90Vac to 264Vac and boost to 380Vdc for the output, there are common choke
FL1001 and FL1002, and CX1001, CX1002 capacitors to form an EMI filter that can reduce noise and interference.
PFC is main for shaping the AC input line current waveform to correspond to that of the AC input line voltage, and boost input rectified voltage to 380Vdc for prerequisite.
The output voltage 5Vsb and 5VC are converted from Standby power, when the system is going to the standby mode,
5Vsb is the only output voltage. After the “Power_ON” (CN2002 Pin1) is high, then other voltage outputs are starting up, otherwise there is only 5Vsb. The 5VC output via Q2006 and under control by 16V depend on Main Power start up, the other outputs voltage +12V, +16V are converted from Main power. They are the main electrical power for whole electrical system.
Short circuit protection
All voltage outputs shall have short circuit protection. Only 5Vsb output shall be auto recovery after the short condition removed.
Over voltage protection
All voltage outputs shall have over voltage protection, 6.24V for 5.25V on 5Vsb outputs; 14.9V for 12V on 12V outputs; 16V will go follow 12V protection; 415V for 380V output.
Under voltage protection
All voltage outputs shall have under voltage protection, besides +/-20V and 380V outputs (4.12V for 5.1V on 5Vsb outputs, 9.7V for 12V on 12V outputs.)

The DDP1011 is designed to work in conjunction with a single 128Mbit or 256Mbit RDRAM™ (Direct RAMBUS(TM) DRAM) and an associated Direct RAMBUS™ Clock Generator (DRCG) chip. For maximum flexibility, the DDP1011 micro-controller operates entirely from a single external Flash device. This Flash provides micro-code, configuration parameters and PWM sequences.
4.3.2 DMD
0.45 inch diagonal spatial light modulator of aluminum micro-mirrors. Display resolution is 1280 columns by 720 rows in a
35
Diagonal Pixel Arrangement. Low Voltage Differential Signaling (LVDS) data interface, Double Data Rate (DDR). Pixel
Architecture is SPD with DarkChip3™.
4.3.3 DAD1000
The DAD1000 (IC9021) DMD Power and Reset Driver provides the high-voltage power supplies and phased reset driver functions for a family of Digital Micro-mirror Devices (DMDs). The DAD1000 is programmable and controllable to meet all current and anticipated DMD requirements.
The high-voltage power supply function generates the three required DMD voltage levels: VBIAS, VRESET, and
VOFFSET. These three supplies are programmed and controlled through a TTL and CMOS compatible serial interface. The
DAD1000 also contains a +5 volt supply for internal logic functions and external color wheel control requirements.
The DAD1000 switches outputs between VBIAS, VRESET and VOFFSET voltage levels to form DMD reset waveforms.
VBIAS may be supplied directly to the DMD to bias the border mirrors to the off state. VOFFSET is also supplied directly to the DMD as DMDVCC2. A fourth DMD power supply, DMDVCC, is supplied directly to the DMD by other circuitry.
4.3.4 CYCLONE
SmoothPicture™ is a technique for storing and displacing consecutive subframes of the image to allow the complete frame of data to be projected, generating two on-screen pixels with one DMD mirror. SmoothPicture™ also significantly reduces image pixelization.
