www.DataSheet4U.com GS9090A GenLINX® III 270Mb/s Deserializer for SDI GS9090A Preliminary Data Sheet Key Features SMPTE 259M-C compliant descrambling and NRZI to NRZ decoding (with bypass) DVB-ASI sync word detection and 8b/10b decoding 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 Automatic or manual selection between SMPTE video and DVB-ASI data Single serial digital input buffer with wide input sensitivity and common mode point User selectable additional processing features including: TRS, ANC data checksum, and EDH CRC error detection and correction programmable ANC data detection illegal code remapping Description The GS9090A is a 270Mb/s reclocking deserializer with an internal FIFO. When used in conjunction with one of Gennum’s SDI Cable Equalizers, a receive solution for SD-SDI and DVB-ASI applications can be realized. In addition to reclocking and deserializing the input data stream, the GS9090A 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 reclocker features a very wide Input Jitter Tolerance, and is fully compatible with both SMPTE and DVB-ASI input streams. The GS909...
