The CH7016A is a Display Controller device which accepts

a digital graphics input signal, and encodes and transmits data

through a 10-bit high speed DAC. The device is able to

encode the video signals and generate synchronization signals

for NTSC and PAL TV standards (SDTV), as well as analog

HDTV interface standards and graphics standards up to

UXGA. The device accepts data over one 12-bit wide

variable voltage data port which supports 5 different data

formats including RGB and YCrCb.

The TV-Out processor will perform non-interlace to interlace

conversion with scaling and flicker filter, and encode data into

any of the NTSC or PAL video standards. The scaling and

flicker filter is adaptive and programmable to enable superior

text display. Eight graphics resolutions are supported up to

1024 by 768 with full vertical and horizontal under-scan

capability in all modes. A high accuracy low jitter phase

locked loop is integrated to create outstanding video quality.

ITU-R BT.656 interlaced video can also be input and scan

converted to non-interlaced video.

In addition to TV encoder modes, bypass modes are included

which perform color space conversion to HDTV standards

and generate and insert HDTV sync signals, or output VGA

style analog RGB for use as a CRT DAC.
