The ISL98001 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 and QXGA, while the front end's programmable input

bandwidth ensures sharp, clear images at all resolutions.

To maximize performance with the widest variety of video

sources, the ISL98001 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.

Glitchless, automatic Macrovision™-compliance is obtained

by a digital Macrovision detection function that detects and

automatically removes Macrovision from the HSYNC signal.

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.

The ISL98001 is fully backwards compatible (hardware and

software) with the X980xx family of AFEs.
