Features 205 million pixels/s conversion rate Digitally programmed gain and offset for red, green and blue color balancing Compatible with RGB and YUV/YPbPr video signals Output format supports 4:2:2 video pulldown Description The ADCS9888 is a high performance Analog Front End (AFE) for digital video applications at resolutions up to UXGA. It performs all the analog and mixed signal functions necessary to digitize a variety of computer and component video sources. The ADCS9888 has a 3 channel, 8 bit 205 MHz ADC with full DC restoration and gain/offset compensation. Full processing of synchronization signals is included with on-chip PLL locked to the pixel rate. Digital sync and analog sync-on-green signals are supported. Flexible data output modes support a variety of downstream data capture and processing applications. Key Specification Output data resolution 8 bits x 3 channels Maximum pixel conversion rate 205 MHz Analog input bandwidth (typical) 500 MHz PLL clock jitter (typical) 570 ps p-p Analog supply voltage 3.0 V to 3.6 V I/O supply voltage 2.2 V to 3.6 V Power dissipation (typical) 1.3W Applications LCD flat panel monitors Video projectors Plasma display panels Video capture hardware RGB and YUV video processing
