File Size : 116 KB Manufacturer:80 Description:Chrontels 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 TrueScaleTM 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 I2C port, to enable a complete PC solution using a TV as the primary display.
