GS2975A HD-LINX III Multi-Rate SDI Automatic Reclocker with Dual Differential Outputs Features Description SMPTE 424M, 292M, and 259M-C compliant The GS2975A is a Multi-Rate Serial Digital Reclocker designed to automatically recover the embedded clock Supports data rates of 270, 1483.5, 1485, 2967, from a digital video signal and re-time the incoming video 2970Mb/s data. Supports DVB-ASI at 270Mb/s The GS2975A Serial Digital Reclocker will recover the Pb-free and RoHS Compliant embedded clock signal and re-time the data from a SMPTE Auto and Manual Modes for rate selection 424M, SMPTE 292M, or SMPTE 259M-C compliant digital Standards indication in Auto Mode video signal. 4:1 input multiplexer patented technology The GS2975A removes the high frequency jitter Choice of dual reclocked data outputs or one data components from the bit-serial stream. Input termination is output and one recovered clock output on-chip for seamless matching to 50 transmission lines. Footprint and drop-in compatible with existing The GS2975A can operate in either auto or manual rate GS2975 designs selection mode. In Auto mode the device will automatically Loss of Signal (LOS) Output detect and lock onto incoming SMPTE SDI data signals at Lock Detect Output any supported rate. For single rate data systems, the GS2975A can be configured to operate in Manual mode. In On-chip Input and Output Termination both modes, the device requires only one external crystal to Differential 50 inputs and outputs set the VCO frequency when not locked and provides Mute, Bypass and Autobypass functions adjustment free operation. SD/HD indication output to control GS2978 Dual In systems which require passing of non-SMPTE data rates, Slew-Rate Cable Driver the GS2975A can be configured to either automatically or Single 3.3V power supply manually enter a bypass mode in order to pass the signal Operating temperature range: 0C to 70C without reclocking. The GS2975A offers a choice of dual reclocked data outputs Applications or one data output and one recovered clock output. The SMPTE 424M, SMPTE 292M and SMPTE 259M-C Serial device is footprint and drop-in compatible with existing Digital Interfaces GS2975 designs, with no additional application changes required. The GS2975A is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous sub-components are RoHS compliant.
