Multi-Rate SDI Automatic Reclocker with Dual Differential OutputsDesigned to automatically recover the embedded clock from a digital video signal and re-time the incoming video data

Overview:

The GS1675 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 292M or SMPTE 259M-C compliant digital video signal.

The GS1675 can operate in either Auto or Manual rate selection mode. In Auto mode, the device will automatically detect and lock onto incoming SMPTE SDI data signals at SD and HD data rates. For single-rate data systems, the GS1675 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 non-SMPTE data rates, the GS1675 can be configured to either automatically or manually enter a bypass mode in order to pass the signal without reclocking.

The GS1675 accepts industry-standard differential input levels including LVPECL and CML. The differential data and clock outputs feature selectable output swing via the host interface, ensuring compatibility with most industry-standard, terminated differential receivers. The GS1675 features dual differential outputs. The second output can be configured to emit either the recovered clock signal or the re-timed video data.
