Multiplexer simultaneously switches many video signals in different formats

Milpitas, Calif.—Intersil Corp. announced the ISL59450 multiformat vdeo multiplexer with integrated sync separator, a device designed for the variety of video signals and formats used today.

The ISL59450 has 6 Composite, 4 S-Video and 4 Component video inputs enabling simultaneously switching of many video signals in different formats. Additionally, two of the Component input channels can be configured for RGB signals with separate horizontal and vertical syncs. This allows for handling of PC video signals often used in multimedia and home-theater applications.

The ISL59450 features integrated programmable anti-aliasing filters, which provide the ability to program the corner frequencies to specifically address the video standard being used.

Two universal sync separators extract the timing signals from input signals, which will be needed further down the signal path to display and manipulate images. This, along with two active output channels per input group, enables functionality such as picture-in-picture (PIP).

The ISL59450 also features programmable output gain control providing another degree of flexibility as the end user can independently adjust the gain of each output to match the termination network.

To support very high resolution signals, the ISL59450 can be configured to bypass the filters and provide 275MHz of bandwidth. Enhanced scalability is achieved through a high impedance state that allows non-active parts to be isolated from active signals, enabling multiple devices to be used in parallel to create larger switches.

Pricing: $7.93 per unit in 1,000-unit quantities.
Availability: Now in a 128-lead MQFP package.
