The TW8804 LCD Flat Panel Controller is a low cost high quality TFT

panel controller with an embedded NTSC/PAL/SECAM TV decoder. This

unique level of mixed signal integration enables the panel to be used as a

stand-alone analog TV. An integrated YPbPr/RGB component input allows

direct connection to DVD, PIP and TTX sources. Separate digital inputs

allow it to be used as a high quality computer monitor when combined

with additional ICs. It incorporates easy-to-operate and powerful features

in a single package for LCD TV, multi-purpose LCD Monitor, Portable DVD

Players and Car Display Entertainment Systems.

The TW8804 contains all the logic required to convert standard TV, DTV,

and PC monitor signals to the digital control and data signals required to

drive various TFT panel types. It supports TFT panel resolutions up to 1280

by 1024 (SXGA/WXGA) with either 1 or 2-pixel/clock formats.

The chip accepts CVBS (composite) analog input or S-video analog input

or YPbPr input for use as a video monitor. Up to four physical CVBS inputs

or one S-video input or one component input can be connected

synchronously with component (RGB or YPbPr) input via fast blanking and

switched

The integrated analog front-end contains six ADCs with ve clamping

circuits and one Automatic Gain Control (AGC) circuit to minimize external

component count. It employs a 2/4H, 5-line adaptive comb lter and

proprietary Y/C processing technologies to produce exceptionally high

quality pictures.

The chip's internal logic synchronizes the panel frame rate to the incoming

input frame rate. A high quality image-scaling engine is used to convert

the lower resolution formats or high resolution DTV formats to the output

panel resolution. An internal de-interlacing engine also allows interlaced

video to be supported.

On Screen Display is supported through either external OSD chip or on-

chip OSD RAM for maximum exibility. A Closed Caption decoder is built

in. The TW8804 also accepts a 24 bit digital RGB input from external

PanelLinkTM receiver or ADCs for use as computer monitor. In addition, it

accepts 8/16/24 bits digital YCbCr input for use with external ADCs for use

as a DTV monitor.

The TW8804 also supports TFT panel power sequencing, DPMS Display

Power Management Signaling) signaling and power management. The

control interface is a 2-wire serial bus interface. The TW8804 core operates

at 2.5 V, the IO at 3.3 V and is packaged in a 160-pin PQFP package.
