Enabling or disabling each of these options will complete SMPTE processing. The SMPTE processing offer power consumption levels to suit the application s features can be bypassed to support signals with other requirements. coding schemes. Multi-link UHD can be supported when multiple GS3470 devices are used. The device has three other basic modes of operation which include: The device features a dual input buffer with a 2x2 MUX. The 2x2 MUX can select between either input for SMPTE mode de-serialization and can route either of the two inputs to the DVB-ASI mode serial loopback independently (reclocked or Data-Through mode non-reclocked). In addition, the integrated Retimer with an The GS3470 includes an audio de-embedder and audio internal VCO provides a wide Input Jitter Tolerance (IJT). clocks are internally generated. Up to eight channels (two Configurable Power-down modes are available and allows audio groups) of serial digital audio may be extracted from for increased flexibility. Each Power-down mode enables the video data stream, in accordance with SMPTE ST 272-C power savings to a varying degree by selectively enabling and SMPTE ST 299. or disabling key features.
