Semtech Corporation GS6042
The GS6042 is a high-speed BiCMOS device designed to optimally equalize and restore signals received over 75Ω coaxial cable. The device supports data rates up to 6.25Gb/s while being optimized for the proposed SMPTE ST 2081, as well as SMPTE ST 424, SMPTE ST 292, and SMPTE ST 259. The GS6042 features DC restoration to compensate for the DC content of SMPTE pathological signals.FEATURES
