Video multiplexer from Intersil combines multiformat video filtering, two universal sync separators and programmable output gain control

The ISL59450 has six Composite, four S-Video and four 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-theatre applications.

The ISL59450 features integrated programmable anti-aliasing filters that provide the ability to program the corner frequencies to specifically address the video standard being used. This further enables the customer to achieve the best possible video performance.
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.

All of this makes the ISL59450 an ideal part to handle multiple video inputs into almost any type of video system.
