CH7022数据手册Chrontel中文资料规格书

描述 Description

The CH7022 is a Display Controller device which accepts a digital graphics high speed AC coupled serial differential RGB input signal, and encodes and transmits data through analog SDTV ports (analog composite, s-video, VGA or YPrPb) or an analog EDTV/HDTV port (YPrPb). The device is able to encode the video signals and generate synchronization signals for NTSC, PAL and SECAM SDTV standards, as well as analog EDTV and HDTV interface standards and graphics standards up to UXGA. The device accepts one channel of RGB data over three pairs of serial data ports.
The TV-Out processor will perform scaling to convert VGA frames to all the supported TV output standards. Adaptive deflicker filter provides superior text display. Large numbers of input graphics resolutions are supported up to 160 MHz pixel rate with full vertical and horizontal overscan compensation in all output standards. A high accuracy low jitter phase locked loop is integrated to create outstanding video quality.
In addition to scaling modes, bypass modes are included which perform color space conversion to all the TV standards and generate and insert all the TV sync signals, or output VGA style analog RGB.
Different analog video connectors are supported including composite, s-video, YPrPb, SCART, D-connector and VGA connector.
CGMS-A is also provided up to 1080i resolution.
CH7022 is a chip without Macrovision™ encoding.
