Cypress Semiconductor Corp. has added two new multirate video cable equalizers to its portfolio of solutions for the professional video equipment market.

The new HD/SD/DVB-ASI video equalizers are targeted for applications with shorter cable lengths, while the new SD/DVB-ASI video equalizers address broadcasting equipment requiring only SD-SDI or DVB-ASI bit-rates. The devices offer an easy-to-implement, complete port solution in professional video equipment designs such as PC video capture cards, video switchers, video routers, logo generators, satellite decoders and DVB-ASI encoder/decoders.

Both equalizers are said to deliver industry best jitter performance and have 160mW typical power consumption with a 3.3V power supply, offering power savings of up to 30 percent over competing solutions. The SD/DVB-ASI video equalizers removes inter-symbol interference from video signals traveling over a cable, and use adaptive equalization to support different cable lengths up to 350m. The HD/SD/DVB-ASI video equalizers also use adaptive equalization to drive equalized SD signals up to 350m on coaxial cable and HD signals up to 140m.

The SD/DVB-ASI equalizers are compliant with SMPTE 259M and DVB-ASI data rates, while the HD/SD/DVB-ASI equalizers are compliant with SMPTE 292M, 344M and 259M, as well as DVB-ASI. The superior eye diagram characteristics of the equalizers allow for more forgiving board design, such as longer trace lengths and other less-than-optimal board conditions. The devices are pin-compatible with existing solutions, giving an easy migration path without board redesigns.

The HD/SD/DVB-ASI video equalizer is offered in a 16-pin SOIC package (CYV15G0100EQ) and a 16-pin QFN package (CYV15G0103EQ). The SD/DVB-ASI video equalizer is available in a 16-pin QFN package (CYV270M0104EQ) and a 16-pin SOIC package (CYV270M0101EQ). All devices are currently in production.

Cypress will demonstrate its complete video interface solution, including the HOTLink-On-Demand family of video Serdes, multi-format equalizers, and cable drivers at IBC 2007 held at the RAI Convention Centre, Amsterdam, Netherlands from September 6-10.
