Description
The GS2962 is a complete SDI Transmitter, generating a
SMPTE 424M, SMPTE 292, SMPTE 259M-C or DVB-ASI
compliant serial digital output signal.
The integrated narrow-BW PLL 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 GS2962 performs all SMPTE
processing features. Both SMPTE 425M Level A and Level B
formats are supported with optional conversion from Level
A to Level B for 1080p 50/60 4:2:2 10-bit.
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 GS2962 integrates a fully SMPTE-compliant Cable
Driver for SMPTE 259M-C, SMPTE 292 and SMPTE 424M
interfaces. It features automatic dual slew-rate selection,
depending on 3Gb/s or HD or SD operational requirements.
