INTEGRATED CIRCUITS DATA SHEET SAA7167 YUV-to-RGB Digital-to-Analog Converter (DAC) Preliminary specification Supersedes data of 1995 Jun 13 File under Integrated Circuits, IC22 1995 Nov 03 Philips Semiconductors Preliminary specification YUV-to-RGB Digital-to-Analog Converter (DAC) 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 andRGB 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. GENERAL DESCRIPTION The SAA7167 is a mixed-mode designed IC containing a video data path, keying control block, analog mixer, and a QUICK REFERENCE DATA SYMBOL VDDD VDDA Tamb digital supply voltage analog supply voltage operating ambient temperature PARAMETER MIN. 4.75 4.75 0 SAA7167 voltage output amplifier, capable of converting digital video data to analog RGB video, and then mixing video and external analog RGB inputs. The video data path contains a data re-formatter, YUV-to-RGB colour space matrix as well as triple DACs for video data processing. An analog mixer performs multiplexing between DAC outputs of the video path and external analog RGB inputs. The final analog outputs are buffered with built-i...
