Triple Video Digitizer with Digital PLL

Features

The ISL98002 3-Channel, 8-bit Analog Front End (AFE)

contains all the functions necessary to digitize analog YPbPr

video signals and RGB graphics signals from DVD players,

digital VCRs, video set-top boxes, and personal computers.

This product family’s conversion rates support HDTV

resolutions up to 1080p and PC monitor resolutions up to

UXGA, while the front end's programmable input bandwidth

ensures sharp, clear images at all resolutions.

• 140MSPS and 170MSPS maximum conversion rates

• Glitchless Macrovision®-compliant sync separator

• Extremely fast recovery from VCR head switching

• Low PLL clock jitter (250ps peak-to-peak @ 170MSPS)

• 64 interpixel sampling positions

• 0.35V

to 1.4V

video input range

P-P

To maximize performance with the widest variety of video

sources, the ISL98002 features a fast-responding digital PLL

(DPLL), providing extremely low jitter with PC graphics signals

and quick recovery from VCR head switching with video

signals. Integrated HSYNC and SOG processing eliminate the

need for external slicers, sync separators, Schmitt triggers,

and filters.

• Programmable bandwidth (100MHz to 780MHz)

• RGB 4:4:4 and YUV 4:2:2 output formats

• Low power (535mW @ 170MSPS)

• Small 10mmx10mm 72 Ld QFN package

• Completely independent 8-bit gain/10-bit offset control

• Pb-free (RoHS Compliant)

Glitchless, automatic Macrovision®- compliance is obtained

by a digital Macrovision® detection function that detects and

automatically removes Macrovision® from the HSYNC

signal.

Applications

• Digital TVs

• Projectors

Ease of use is also emphasized with features such as the

elimination of PLL charge pump current/VCO range

programming and single-bit switching between RGB and

YPbPr signals. Automatic Black Level Compensation

(ABLC™) eliminates part-to-part offset variation, ensuring

perfect black level performance in every application.

• Multifunction Monitors

• Digital KVM

• RGB Graphics Processing
