Intersil Ensures Black-Level Consistency with 32x16 Video Crosspoint

-- Intersil's ISL59534, 300 MHz 32x16 Video Crosspoint with Integrated DC-Restore Clamp Delivers Black-Level Accuracy with at least 32 Fewer External Devices than Competitive Solutions

MILPITAS, CA, September 13, 2006 – Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today introduced a new 32x16 video crosspoint switch. The ISL59534 integrates a DC-restore clamp on each video input to eliminate black-level fluctuation, providing correctly balanced composite video with fewer external components.

The DC-restore clamp biases composite (NTSC and PAL) video by automatically adjusting the DC level of the most negative portion of the video to the reference voltage. This feature can be disabled by the user through an SPI/QSPITM compatible, three-wire serial interface for S-video and component video applications.

“Intersil’s ISL59534 crosspoint switch provides black-level accuracy in composite video,” said Kathryn Tucker, marketing manager for Intersil’s Video products group. “Proper video levels yield better picture quality and our integrated DC-restore function on the chip reduces fluctuation while eliminating pictures that are too light or too dark. The ISL59534 also eliminates the need for diodes, resistors and capacitors on each video input, resulting in cost and board space savings.”

This release adds to Intersil’s expanding video crosspoint switch portfolio which now includes a 32x32 (ISL59532), a 32x16 (ISL59534) and a 16x16 (ISL59530). All of these devices feature integrated DC-restore clamps for superior black-level consistency and are footprint compatible for increased designed flexibility.

Clearer Pictures and Greater Flexibility
The ISL59534 is ideal for routing video signals in security and video-on-demand systems. This device operates from a single +5V supply. It can accommodate voltages from 0V to 3.5V at the inputs and 0V to 4V at the outputs. It also has an input clamp with external group reference that can be used for AC-coupled applications.

Any of the ISL59534’s outputs can be switched to any of the 32 input video signal sources. The device also features a broadcast mode in which any single input can be simultaneously sent to all 16 outputs. With 90MHz of bandwidth in broadcast mode, the ISL59534 is well suited for security applications. Outputs can be individually programmed to high impedance and a gain of +1 or +2 for greater flexibility.

The ISL59534 features a -3dB signal bandwidth of 320MHz. The device has a differential gain and differential phase of 0.025 percent and 0.022 degrees and 0.1dB flatness out to 50MHz. This performance supports increasingly higher video resolutions and provides superior isolation for less leakage between video channels. The device also has a large output current for driving multiple video loads. Each output of the ISL59534 can be put into a high impedance state so that several outputs can be connected together enabling much larger video matrices without adding rows of buffers.

The ISL59534 offers an integrated fast OSD (on-screen display) switch in each output to enable users to switch in other graphics – such as the location of the camera providing the video feed – into the video signal. OSD information can be inserted into any output through an internal, dedicated, fast 2:1 mux (15ns switching times) located before the output buffer. Intersil’s OSD switch performs at speeds necessary for “glitchless OSD,” or video signal switching without any noticeable smudging. The integration of OSD switch further reduces the BOM when compared to other competitive solutions.

Footprint Compatible Crosspoint Switch Family
This device is part of Intersil’s new line of video crosspoint switches that are footprint compatible with our industry-leading, single-chip 32x32 video crosspoint. Customers can use the same board design for a variety of different applications and choose the Intersil crosspoint that best fits their input and output requirements. This gives customers additional flexibility and reduces the need for unique board designs for different applications.

About Intersil's Video Products
From high-performance video amplifiers to differential line equalizers, Intersil's portfolio of video products can address any portion of the analog signal chain. The number and variety of video products on the market continues to grow. With the expansion of HDTV and high-resolution RGB (red, green, blue) signals, the most common point-to-point connection for a video signal is analog. Intersil's video ICs provide many solutions for moving these signals around. Whether it is transmitting RGB down CAT-5 or switching 32 security video feeds, Intersil has a solution. Also, Intersil's ISL5944x family extends the available bandwidth of RGB multiplexers on the market from 500 MHz up to 1GHz – the first time this barrier has been broken. Intersil continues to deliver best-in-class video solutions for its customers, addressing every piece of the signal chain.
