ADCS9888
205/170/140 MSPS Video Analog Front End
General 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 compen-
sation. 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.
