The ISL98003 3-channel, 8-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 8-bit performance and a 165MSPS maximum
conversion rate supporting resolutions up to 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 ISL98003
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 ISL98003'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.
