GS9092A GenLINX III 270Mb/s Serializer for SDI and DVB-ASI Key Features Description SMPTE 259M-C compliant scrambling and NRZI to NRZ The GS9092A is a 270Mb/s serializer with an internal FIFO encoding (with bypass) and an integrated cable driver. It contains all the necessary blocks to realize a transmit solution for SD-SDI and DVB-ASI sync word insertion and 8b/10b encoding DVB-ASI applications. Integrated Cable Driver In addition to serializing the input data stream, the Integrated line-based FIFO for data alignment/delay, GS9092A performs NRZI-to-NRZ encoding and scrambling clock phase interchange, DVB-ASI data packet as per SMPTE 259M-C when operating in SMPTE mode. insertion, and ancillary data packet insertion When operating in DVB-ASI mode, the device will insert User selectable additional processing features K28.5 sync characters and 8b/10b encode the data prior to including: serialization. ANC data checksum, and line number calculation Parallel data inputs are provided for 10-bit multiplexed and insertion formats at SD signal rates. A 27MHz parallel clock input TRS and EDH packet generation and insertion signal is also required. illegal code remapping The integrated cable driver features an adjustable signal Enhanced Gennum Serial Peripheral Interface (GSPI) swing and common mode operating point offering fully JTAG test interface compliant SMPTE 259M-C cable driver connectivity. +1.8V internal cable driver and core power supply The GS9092A includes a range of data processing functions Optional +1.8V or +3.3V digital I/O power supply such as automatic standards detection and EDH support. Small footprint (8mm x 8mm) The device can also insert TRS signals, re-map illegal code words, and generate and insert SMPTE 352M payload Low power operation (typically 200mW) identifier packets. All processing features are optional and Pb-free and RoHS compliant may be enabled/disabled via external control pin(s) and/or host interface programming. Applications The GS9092A also incorporates a video line-based FIFO. SMPTE 259M-C Serial Digital Interfaces This FIFO may be used in four user-selectable modes to DVB-ASI Serial Digital Interfaces carry out tasks such as data delay, clock phase interchange, MPEG packet insertion and clock rate interchange, and ancillary data packet insertion. The device may also be used as a low-latency parallel-to-serial converter where the SMPTE scrambling block will be the only processing feature enabled. The GS9092A is Pb-free, and the encapsulation compound does not contain halogenated flame retardant (RoHS compliant).
