General Description
The CH7021A is a Display Controller device which accepts
a digital graphics high speed AC coupled serial differential
RGB input signal, and encodes and transmits data through
analog SDTV ports (analog composite, s-video, RGB or
YPrPb) or an analog HDTV port (YPrPb). The device is able
to encode the video signals and generate synchronization
signals for NTSC, PAL and SECAM SDTV standards, as
well as analog HDTV interface standards and graphics
standards up to UXGA. The device accepts one channel of
RGB data over three pairs of serial data ports.
The TV-Out processor will perform scaling to convert VGA
frames to supported SDTV and HDTV output standards.
Adaptive de-flicker filter provides superior text display. Large
numbers of input graphics resolutions are supported up to
1600 by 1200 with full vertical and horizontal overscan
compensation in all output standards. A high accuracy low
jitter phase locked loop is integrated to create outstanding
video quality.
In addition to scaling modes, bypass modes are included
which perform color space conversion to SDTV or HDTV
standards and generate and insert SDTV or HDTV sync
signals, or output VGA style analog RGB for use as a CRT
DAC.
Different analog video connectors are supported including
composite, s-video, YPrPb, SCART, D-connector and VGA
connector.
Content protection support is provided for Macrovision

in
SDTV and EDTV modes. CGMS-A is also provided up to
1080i resolution.
