The GS1535 Multi-Rate Serial Digital Reclocker is designed to automatically recover the embedded clock signal and re-time the data from a SMPTE 292M, SMPTE 259M or SMPTE 344M compliant digital video signal.
The device removes the high frequency jitter components from the bit-serial stream. Input termination is on-chip for seamless matching to 50 ohm transmission lines. An LVPECL compliant output interfaces seamlessly to the GS1528 Cable Driver.
The GS1535 can operate in either auto or manual rate selection mode. In Auto mode the GS1535 automatically detects and locks onto an incoming SMPTE SDI data signal from 143 Mb/s to 1.485 Gb/s. For single rate data systems, the GS1535 can be configured to operate in manual mode. In both modes, the GS1535 requires only one external crystal to set the VCO frequency when not locked and provides adjustment free operation. In systems which require passing non-SMPTE data rates, the GS1535 will automatically or manually enter a bypass mode in order to pass the signal without reclocking.
The ASI/177 input pin allows for manual selection of support of either 177Mb/s or DVB-ASI inputs.
