GS2972
Overview
The GS2972 is a complete SDI transmitter, generating a SMPTE 424M, 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 GS2972 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 GS2972 includes a fully SMPTE-compliant cable driver for SMPTE 259M-C, SMPTE 292M and SMPTE 424M interfaces. It features automatic dual slew-rate selection, depending on 3G-, HD- or SD-SDI operational requirements.
In accordance with SMPTE 272M and SMPTE 299M, up to eight channels (two audio groups) of serial digital audio may be embedded into the video data stream. The input audio signal formats supported by the device include AES/EBU, I2S and serial audio. 16, 20 and 24-bit audio formats are supported at 48kHz synchronous for SD modes and 48kHz synchronous or asynchronous in HD, 3Gb/s modes.
