ADCS9888 Datasheet | National Semiconductor

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 puter and ponent video sources. The ADCS9888 has a 3 channel, 8 bit 205 MHz ADC with full DC restoration and gain/offset pensation. 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. n Output format supports 4:2:2 video pulldown Key Specifications n n n n n n n Output data resolution Maximum pixel conversion rate Analog input bandwidth (typical) PLL clock jitter (typical) Analog supply voltage I/O supply voltage Power dissipation (typical) 8 bits x 3 channels 205 MHz 500 MHz 570 ps p-p 3.0 V to 3.6 V 2.2 V to 3.6 V 1.3W Applications n n n n n LCD flat panel monitors Video projectors Plasma display panels Video capture hardware RGB and YUV video processing Features n 205 million pixels/s conversion rate n Digitally programmed gain and offset for red, green and blue color balancing n patible with RGB and YUV/YPb Pr video signals Typical Application Ordering Information Temperature Range 0˚C ≤ TA ≤ +70˚C Order Number ADCS9888CVH1-205 ADCS9888CVH1-170 ADCS9888CVH1-140 Notes:1 - Tray transport media, 66 parts per tray.
