描述
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 a sampling clock jitter of 250ps peak-to-peak (p-p).
