GS2975A HD-LINX® III Multi-Rate SDI Automatic Reclocker with Dual Differential Outputs Features - - - - - - - - - - - - - - - - - SMPTE 424M, 292M, and 259M-C pliant Supports data rates of 270, 1483.5, 1485, 2967, 2970Mb/s Supports DVB-ASI at 270Mb/s Pb-free and Ro HS pliant Auto and Manual Modes for rate selection Standards indication in Auto Mode 4:1 input multiplexer patented technology Choice of dual reclocked data outputs or one data output and one recovered clock output Footprint and drop-in patible with existing GS2975 designs Loss of Signal (LOS) Output Lock Detect Output On-chip Input and Output Termination Differential 50Ω inputs and outputs Mute, Bypass and Autobypass functions SD/HD indication output to control GS2978 Dual Slew-Rate Cable Driver Single 3.3V power supply Operating temperature range: 0°C to 70°C Description The GS2975A is a Multi-Rate Serial Digital Reclocker designed to automatically recover the embedded clock from a digital video signal and re-time the ining video data. The GS2975A Serial Digital Reclocker will recover the embedded clock signal and re-time the data from a SMPTE 424M, SMPTE 292M, or SMPTE 259M-C pliant digital video signal. The GS2975A removes the high frequency jitter ponents from the bit-serial stream. Input termination is on-chip for seamless matching to 50Ω transmission lines. The GS2975A can operate in either auto or manual rate selection mode. In Auto mode the device will automatically detect and lock onto ining SMPTE SDI data signals at any supported rate. For single rate data systems, the GS2975A can be configured to operate in Manual mode. In both modes, the device requires only one external crystal to set the VCO frequency when not locked and provides adjustment free operation. In systems which require passing of non-SMPTE data rates, the GS2975A can be configured to either automatically or manually enter a bypass mode in order to pass the signal without reclocking. The GS2975A offers a...
