AE S OUT 7/8 Analog Sync HVF/PCLK Sync GS4911 Seperator Audio Clocks In SMPTE mode (the default operating mode), the GS2971A performs full SMPTE processing, and features a number of data integrity checks and measurement capabilities. The device also supports ancillary data extraction, and can Application: Multi-format Audio De-embedder Module provide entire ancillary data packets through 10-bit host-accessible registers. It also provides a variety of other GS2962 SD/HD/3G-SDI packet detection and error handling features. All of these PCLK processing features are optional, and may be individually SD/HD/3G-SDI GS2971A AES AUDIO 1/ 2 Audio Switch AUDIO 3/ 4 Outputs enabled or disabled through register programming. Logic AUDIO 5/ 6 & AUDIO 7/ 8 Drivers DAC Analog Audio Clocks Audio Both SMPTE ST 425 Level A and Level B inputs are Outputs supported with optional conversion from Level B to Level A for 1080p 50/59.94/60 4:2:2 10-bit inputs. In DVB-ASI mode, sync word detection, alignment and 8b/10b decoding is applied to the received data stream. Application: Multi-format Digital VTR/Video Server In Data-Through mode all forms of SMPTE and DVB-ASI V ideo Output processing are disabled, and the device can be used as a 10-bit simple serial to parallel converter. Video Processor HVF/PCLK Storage: The device can also operate in a lower power Standby Tape/HDD/Solid State SD/HD/3G-SDI GS2971A AUDIO 1/2 AUDIO 3/4 AUDIO 5/6 Audio mode. In this mode, no signal processing is carried out and AUDIO 7/8 Processor Audio Clocks the parallel output is held static. Audio Outputs Parallel data outputs are provided in 20-bit or 10-bit format for 3Gb/s, HD and SD video rates, with a variety of mapping options. As such, this parallel bus can interface directly with video processor ICs, and output data can be multiplexed Description onto 10 bits for a low pin count interface. The GS2971A is a multi-rate SDI integrated Receiver which includes complete SMPTE processing, as per SMPTE ST 425, Up to eight channels (two audio groups) of serial digital SMPTE ST 292 and SMPTE ST 259-C. The SMPTE processing audio may be extracted from the video data stream, in features can be bypassed to support signals with other accordance with SMPTE ST 272-C and SMPTE ST 299. coding schemes. The output audio formats supported by the device include 2 The GS2971A integrates Semtech s adaptive cable equalizer AES/EBU and I S, and two other industry standard serial technology, achieving unprecedented cable lengths and digital formats. A variety of audio processing features are jitter tolerance. It features DC restoration to compensate for provided to ease implementation. Audio clocks are the DC content of SMPTE pathological signals. internally generated and provided by the device.
