Semtech GS12090 UHD-SDI Cable Equalizer & Driver

Semtech GS12090 Ultra High Definition (UHD)-Serial Digital Interface (SDI) Cable Equalizer and Driver is a low-power, configurable, multi-rate retiming device. This retiming device can be configured to equalize or drive signals over a 75Ω coaxial cable. The integrated eye monitor provides a non-disruptive mission mode analysis, and the 256 x 128 resolution scan matrix allows accurate signal analysis. Semtech GS12090 equalizer/driver includes Digital Cinema (DC) restoration to compensate for the DC content of Society of Motion Picture and Television Engineers (SMPTE) pathological test patterns. This retiming device achieves low output jitter even at extended cable length and provides multi-standard operation from 1Mbps to 11.88Gbps.

The GS12090 equalizer/driver is a single bidirectional 75Ω cable interface with on-chip termination and provides user-selectable output slew rate control. This retiming device's pin is compatible with the GS3590 bi-directional cable equalizer/cable drive. The GS12090 equalizer/driver finds its applications in next-generation 3D/2D High Frame Rate (HFR) HDTV and 2K Digital Cinema, UHDTV1, and 4K D-Cinema.
