ISL98001 FN6148
Rev 5.00
September 21, 2010 Triple Video Digitizer with Digital PLL
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. Features 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. 64 intrapixel sampling positions 140MSPS, 170MSPS, 210MSPS, and 275MSPS
maximum conversion rates Glitchless Macrovision-compliant sync separator Extremely fast recovery from VCR head switching Low PLL clock jitter (250psP-P @ 170MSPS) 0.35VP-P to 1.4VP-P video input range Programmable bandwidth (100MHz to 780MHz) 2-channel input multiplexer RGB 4:4:4 and YUV 4:2:2 output formats 5 embedded voltage regulators allow operation from
single 3.3V supply and enhance performance, isolation Glitchless, automatic Macrovisionв„ў-compliance is obtained
by a digital Macrovision detection function that detects and
automatically removes Macrovision from the HSYNC signal. Completely independent 8-bit gain/10-bit offset control Pb-free (RoHS compliant) Ease-of-use is also emphasized with features such as the
elimination of PLL charge pump current/VCO range …
