The ISL51002 3-channel, 10-bit Analog Front End (AFE) contains all the functionality needed to digitize analog YPbPr video from HDTV tuners, set top boxes, SD and HD DVDs, as well as RGB graphics signals from personal computers and workstations. The fourth generation analog design delivers 10-bit performance and a 165MSPS maximum conversion rate supporting resolutions up to 1080p/UXGA at 60Hz. The front end's programmable input bandwidth ensures sharp, low noise images at all resolutions.

To accelerate and simplify mode detection, the ISL51002 integrates a sophisticated set of measurement tools that fully characterizes the video signal and timing, offloading the host microcontroller. Automatic Black Level Compensation (ABLC™) eliminates
part-to-part offset variation, ensuring perfect black level performance in every application.

The ISL51002's Digital PLL generates a pixel clock from the analog source's HSYNC or SOG (Sync-On-Green) signals. Pixel clock output frequencies range from 10MHz to 165MHz with sampling clock jitter of 250ps peak to peak.
