Chrontel’s CH7005 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 true scale scaling and deflickering
engine, the CH7005 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 CH7005 ideal for system-level
PC solutions. All features are software programmable
through a standard serial port, to enable a complete PC
solution using a TV as the primary display.
