ISL51002
Data Sheet February 29, 2012 10-Bit Video Analog Front End (AFE) with
Measurement and Auto-Adjust Features
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
(ABLCв„ў) 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. FN6164.3 Features Automatic sampling phase adjustment 10-bit triple Analog to Digital Converters with
oversampling up to 8x in video modes 165MSPS maximum conversion rate (ISL51002CQZ-165) Robust, glitchless MacrovisionВ®-compliant sync separator Analog VCR “Trick Mode” support ABLCв„ў for perfect black level performance 3 channel input multiplexer Precision sync timing measurement RGB to YUV color space converter Low PLL clock jitter (250ps p-p) Programmable input bandwidth (10MHz to 450MHz) 64 interpixel sampling positions В±6dB gain adjustment rate Pb-free (RoHS compliant) Related Literature Applications Technical Brief TB363 “Guidelines for Handling and …
