Cypress Semiconductor Corp. announced two new multirate video cable equalizers targeted at the professional video market. The new devices complement the company's HOTLink-On-Demand family of high-speed video Serdes (as well as other Serdes), offering an easy-to-implement complete port solution in professional video equipment designs, including production switchers, distribution amplifiers, D/A converters and camera control units.

The CYV15G0102 delivers standard definition (SD) signals over greater than 400m and high-definition (HD) signals over greater than 200 meters. These specifications compare to the industry-standard distance range of 100 meters for HD and 300 meters for SD signals. The CYV15G0101 equalizer is guaranteed to drive equalized SD signals over 300m of coaxial cable, and HD signals over 100m. In addition, the CYV15G0101/2 devices offer a power savings of 40 percent over competing solutions, typically an important feature in video systems requiring multiple input SDI links such as production switchers and video routers, said Cypress.

"The new equalizers offer the industry's best performance along with a standard pinout that eases the design process," said Erin Kettwig, product manager for Cypress' physical layer devices. "In conjunction with the HOTLink-On-Demand family of video Serdes and YLink products, we now offer video equipment designers an economical, robust suite of products for next-generation systems."

The press release states that the superior eye diagram characteristics of the CYV15G0101/2 allow for more forgiving board design, such as longer trace lengths and other less-than-optimal board conditions. These new products support launch amplitudes from 500mV to 1.2V at HD rates, allowing equalization to be independent of the transmitter launch amplitude. This independence offers more system design flexibility and can support system and network anomalies without failure to equalize the data.

The CYV15G0101/2 are offered in Pb-free 16-pin SOIC packages. Pricing in 1,000-unit quantities is $51 each for the CYV15G0101 and $66 each for the CYV15G0102. Samples of these products will be available later this month (September 2005), with full production availability slated for Q1 of 2006.
