描述 Description

GENERAL DESCRIPTION
The SAA7167 is a mixed-mode designed IC containing a video data path, keying control block, analog mixer, and a voltage output amplifier, capable of converting digital video data to analog RGB video, and then mixing video and external analog RGB inputs.FEATURES
• On-chip mixing of digital video data and analog RGB signals
• Supports video input format of YUV 4:2:2, 4:1:1, 2:1:1 and RGB 5:6:5
• Video input rate up to 50 MHz
• Allows for both binary and two’s complement video input data
• Triple 8-bit DACs for video output
• Built-in voltage output amplifier
• Provide keying control with external key and internal 8-bit, 2×8-bit and 3×8-bit pixel colour key
• Programmable via the I2C-bus
• 5 V CMOS device; LQFP48 package.
