GS9091B Datasheet | Gennum

Features - SMPTE 259M-C pliant descrambling and NRZI to NRZ decoding (with bypass) - DVB-ASI 8b/10b decoding - Integrated Cable Equalizer - 500m typical equalization of Belden 1694A cable - Integrated line-based FIFO for data alignment/delay, clock phase interchange, DVB-ASI data packet extraction and clock rate interchange, and ancillary data packet extraction - Integrated VCO and reclocker - User selectable additional processing features including: - TRS, ANC data checksum, and EDH CRC error detection and correction - programmable ANC data detection - illegal code remapping - Internal flywheel for noise immune H, V, F extraction - Automatic standards detection and indication - Enhanced Gennum Serial Peripheral Interface (GSPI) - JTAG test interface - Polarity insensitive for DVB-ASI and SMPTE signals - +1.8V core power supply with optional +1.8V or +3.3V I/O power supply - Small footprint (11mm x 11mm) - Low power operation (typically 350m W) - Pb-free and Ro HS pliant Applications - SMPTE 259M-C Serial Digital Interfaces - DVB-ASI Serial Digital Interfaces Description The GS9091B is a 270Mb/s equalizing and reclocking deserializer with an internal FIFO. It provides a plete receive solution for SD-SDI and DVB-ASI applications. In addition to equalizing, reclocking and deserializing the input data stream, the GS9091B performs NRZI -to-NRZ decoding, descrambling as per SMPTE 259M-C, and word alignment when operating in SMPTE mode. When operating in DVB-ASI mode, the device will word align the data to K28.5 sync characters and 8b/10b decode the received stream. The integrated equalizer is optimized for 270Mb/s and can typically equalize up to 500m of Belden 1694A cable. Both the equalizer and the internal reclocker are fully patible with both SMPTE and DVB-ASI input streams. The GS9091B includes a range of data processing functions such as EDH support (error detection and handling), and automatic standards detection. The device can also detect and extract SMPTE 352M...
