Triple Video Digitizer with Digital PLL
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.
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.
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.
