Adaptive cable EQs provide reach beyond 200 m, offer best density

Three 3-Gbit/s adaptive cable equalizers (EQs) consisting of the GS3440 and its dual-output variant, the GS3441, uniquely combine the industry’s longest reach, while the GS3442 high-density adaptive EQ is optimized for use in high-density multilane environments. The GS3440’s high-speed, low-power integrated circuit design equalizes and restores signals received over 75-Ω coaxial cable, delivering 3-Gbit/s images at distances beyond 200 m.

Identical in performance to the GS3440, the GS3441 adds an additional output, allowing for even greater flexibility in system design. The GS3442 is optimized for use with the latest generation of BNC connector options including HD-BNC, DIN 1.0/2.3 and Mini BNC connectors. Its low sensitivity to crosstalk also makes it an ideal choice for high-density connector solutions such as FCI Densishield.

They all are designed to support SMPTE ST 424, SMPTE ST 292 and SMPTE ST 259 coaxial cable serial digital interfaces, and are optimized for performance at 270 Mbits/s, 1.485 Gbits/s, and 2.97 Gbits/s. Each of the devices are drop-in compatible with all of the EQs in Gennum’s 3-Gbit/s equalizer family.
