Chrontel’s CH7006 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 CH7006 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 CH7006 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.
