Intersil's Video SERDES IC Eliminates Data Control Cables and Increases Signal Distance

ISL34340 27:1 SERDES With Bi-Directional I2C Interface Carries 24 RGB Bits, Three Video Control Bits With a Pixel Clock Rate of 6MHz to 40MHz in a Single High-Speed Data Stream

MILPITAS, CA--(Marketwire - June 25, 2008) - Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today announced the release of the ISL34340. This SERDES Interface transports 27 bits of video data and bi-directional I2C into a single high-speed LVDS cable of up to 10 meters long.

The ISL34340 is ideal for SERDES applications in video systems, industrial and medical displays and video transport in printing and security systems.

The device allows designers to dramatically lower costs and improve video signal distance and reliability through a number of performance and integration enhancements. It has a standard video flow that allows 3x8 (24) RGB bits and three video control bits into a single LVDS pair. This reduces the cost of both the connector and cable and improves EMI/EMC performance. And with bi-directional I2C control, the ISL34340 allows designers to use fewer cables.

Embedded termination resistors in the ISL34340 allow further cost reduction by eliminating discrete resistor requirements.

The ISL34340 improves the reliability of applications with a Lock/Loss detection feature. This recognizes cable disconnects and makes the system more dependable, especially by enabling it to recognize outgoing signal failures.

A DC balanced 8b/10b code in the ISL34340 allows AC coupling and provides immunity against ground shifts. The overall result is improved common mode transmission that enables reliable signal over a greater cable distance. Integrating transmitter pre-emphasis and receiver equalization in the ISL34340 makes longer distance, less-expensive cable use possible by eliminating unwanted signal elements to provide a clearer end-signal transmission.

Pricing and Availability

The ISL34340 is available now in a 64-lead EPTQFP package and is priced at $5.14 each in 1,000-unit quantities.

About Intersil's SERDES/LVDS Products

Intersil is bringing a wide range of SERDES/LVDS solutions to many industries, including automotive, printing, security, industrial and video display. SERDES (SERial/DESerialize) technology is based upon a transmitter and receiver pair that serializes parallel data and deserializes serial data, most often in LVDS format. LVDS (Low Voltage Differential Signal) signals perform at a higher data rate and require less power than any other signaling protocols. Intersil's ISL34340 is leading the way for the developing family of SERDES/LVDS products.
