Overview
GS2965 Multi-Rate SDI Reclocker with Equalization & De-emphasis Features • SMPTE 424M, SMPTE 292M and SMPTE 259M-C compliant • Supports DVB-ASI at 270Mb/s • Single supply operation at 3.
3V or 2.
5V • 180mW typical power consumption (213mW with RCO enabled) at 2.
5V • Input signal equalization and output-signal de-emphasis settings to compensate for board-trace dielectric losses • 2:1 input multiplexer patented technology • Choice of dual reclocked data outputs or one reclocked data output and one clock output • Uses standard 27MHz crystal • Differential inputs and outputs Š support DC coupling to industry-standard differential logic Š on-chip 100Ω differential data input/output termination Š selectable 400mVppd or 800mVppd output swing on each output Š seamless interface to other Gennum products • 4 wire SPI host interface for device configuration and monitoring • Standard logic control and status signal levels • Auto and Manual modes for rate selection • Standards indication in Auto mode • Lock Detect Output • Mute, Bypass and Autobypass functions • SD/HD indication output to control GS2978 or GS2988 dual slew-rate cable drivers • Operating temperature range: -40°C to +85°C • 32 pin 5mm x 5mm QFN package • Pb-free and RoHS compliant Applications • SMPTE 424M, SMPTE 292M and SMPTE 259M-C coaxial cable serial digital interfaces Description The GS2965 is a multi-rate serial digital reclocker designed to automatically recover the embedded clock from a digital video signal and retime the incoming video data.
It will recover the embedded clock signal and retime the data from a SMPTE 424M, SMPTE 292M, or SMPTE 259M-C compliant digital video signal.
A serial host interface provides the ability to configure and monitor multiple GS2965 devices in a daisy-chain configuration.
Adjustable input trace equalization (EQ) for up to 40” of FR4 trace losses, and adjustable output de-emphasis (DE) for up to 20” of FR4 trace losses, can be configured via the host interface.
