Description

Chrontel's CH7007 digital PC to TV encoder is a stand-alone integrated circuit which provides a PC 99 compliant solution for TV output. Suggested application use with the Intel® 810 chipset and Intel® 810E chipset. 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 CH7007 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 CH7007 ideal for system-level PC solutions. All features are software programmable through a serial port, to enable a complete PC solution using a TV as the primary display.
