In this mode, no signal is generated at the output. The GS1672 is a complete SDI Transmitter, generating a SMPTE ST 292, SMPTE ST 259-C, or DVB-ASI compliant serial The GS1672 integrates a fully SMPTE-compliant Cable digital output signal. Driver for SMPTE ST 259-C and SMPTE ST 292 interfaces. It features automatic dual slew-rate selection, depending on The integrated narrow BW PLL allows the device to accept HD or SD operational requirements. parallel clocks with high input jitter, and still provide a SMPTE compliant serial digital output. In accordance with SMPTE ST 272 and SMPTE ST 299, up to eight channels (two audio groups) of serial digital audio The device can operate in four basic user selectable modes: may be embedded into the video data stream.The input SMPTE mode, DVB-ASI mode, Data-Through mode, or audio signal formats supported by the device include Standby mode. 2 AES/EBU, I C and serial audio. 16, 20, and 24-bit audio In DVB-ASI mode, the device will perform 8b/10b encoding formats are supported at 48kHz synchronous for SD modes prior to transmission. and 48kHz synchronous or asynchronous in HD modes. In Data-Through mode, all SMPTE and DVB-ASI processing is disabled. The device can be used as a simple parallel to serial converter.
