Semtech GS1662
The GS1662 is an SDI transmitter, generating a SMPTE 292M, SMPTE 259M-C or DVB-ASI compliant serial digital output signal.
The integrated ClockCleaner™ allows the device to accept parallel clocks with high input jitter, and still provide a SMPTE compliant serial digital output.
The device can operate in four basic user selectable modes: SMPTE mode, DVB-ASI mode, Data-Through mode, or Standby mode.
In SMPTE mode, the GS1662 performs all SMPTE processing features.
In DVB-ASI mode, the device will perform 8b/10b encoding prior to transmission.
In Data-Through mode, all SMPTE and DVB-ASI processing is disabled. The device can be used as a simple parallel to serial converter.
The device can also operate in a lower power Standby mode. In this mode, no signal is generated at the output.
The GS1662 includes a fully SMPTE-compliant cable driver for SMPTE 292M and SMPTE 259M-C interfaces. It features automatic dual slew-rate selection, depending on HD- or SD-SDI operational requirements.
