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 GS2972 performs all SMPTE processing features. Both SMPTE ST 425 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 integrates a fully SMPTE-compliant Cable Driver for SMPTE ST 259-C, SMPTE ST 292 and SMPTE ST 424 interfaces. It features automatic dual slew-rate selection, depending on 3Gb/s or HD or SD operational requirements. In accordance with SMPTE ST 272 and SMPTE ST 299, 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.
