Video Front End Delivers High Bandwidth, Low Jitter and Ideal Black Levels

The ISL98001 triple-channel, video Analogue Front End (AFE) IC from Intersil provides the industry’s highest speeds along with continuously controlled offset voltages, so designers do not have to calibrate offset error out of their system on an AFE-by-AFE basis.



The device’s Digital Phase Locked Loop (DPLL) includes headswitching support, enabling high-performance handling of images even under the worst-case scenario of digitising inputs from a high-definition digital VCR playing back a standard VHS tape.

The ISL98001 is a triple-channel, 8-bit video AFE that incorporates all of the functions required to digitise component video signals and RGB (Red, Green, Blue) graphics signals from DVD players, VCRs, Set-Top Boxes and Personal Computers. It is available in five different speeds ranging from 140Mpixels/s to 275Mpixels/s, providing a solution for every video resolution. The device delivers optimal performance for high-end televisions, monitors, home theatres, business projectors, and KVM (Keyboard, Video, Mouse) products.

The ISL98001’s fast conversion rates support HDTV resolution up to 1080p and computer monitor resolutions up to QXGA. The programmable input bandwidth incorporated in the AFE ensures sharp, clean images at all resolutions. In addition, the device delivers very low jitter, high bandwidth and excellent linearity. Its automatic black level compensation ensures outstanding black level performance for even the lowest cost home theatre systems, delivering excellent colour reproduction even with temperature variations.

The device’s maximum jitter figure of 450ps (250ps typical), achieved via the use of DPLL technology, is the best in the industry and a necessity for PC resolutions of UXGA and higher. A ‘peaking’ function compensates for input degradation in instances of low channel bandwidth, and integrated HSYNC and SOG signal processing eliminates the need for external sync slicers, sync separators, Schmitt triggers and noise filters.

The ISL98001 is available now in 128-lead MQFP packages.
