Front end is comprehensive video digitiser

A triple-channel 8bit video analogue front end incorporates all the functions required to digitise YPbPr video signals and RGB graphics signals from DVD players, VCRs, set-top boxes and PCs.
A triple-channel, video analogue front end 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) even includes headswitching support, enabling high-performance images even under the worst-case scenario of digitising inputs from a high-definition digital VCR playing back a standard VHS tape. Intersil's ISL98001 is a triple-channel, 8bit video analogue front end (AFE) that incorporates all of the functions required to digitise YPbPr (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 140 to 275Mpixel/s, providing a solution for every video resolution.

The device delivers optimal performance for hi-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 ISL98001 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.

One of the most innovative features of the ISL98001 is its digital phase locked loop technology, which allows Intersil to provide a maximum jitter of 450ps (250ps typical) peak-to-peak, the best in the industry and a necessity for UXGA and higher PC resolutions.

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.
