Advanced 170MHz Triple Video Digitizer with Digital PLL

Product Status: Mass Production


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.
