General Description
Chrontel’s CH7004 digital PC to TV encoder is a stand-
alone integrated circuit which provides a PC 99 compliant
solution for TV output. It provides a universal digital input
port to accept a pixel data stream from a compatible VGA
controller (or equivalent) and converts this directly into
NTSC or PAL TV format.
This circuit integrates a digital NTSC/PAL encoder with
9-bit DAC interface, and new adaptive flicker filter, and
high accuracy low-jitter phase locked loop to create
outstanding quality video. Through its TrueScale
scaling and de-flickering engine, the CH7004 supports full
vertical and horizontal underscan capability and operates
in 5 different resolutions including 640x480 and 800x600.
A new universal digital interface along with full
programmability make the CH7004 ideal for system-level
PC solutions. All features are software programmable
through a standard I
solution using a TV as the primary display.
