Description
The GS9092 is a 270Mb/s serializer with an internal FIFO and an integrated cable driver. It contains all the necessary blocks to realize a transmit solution for SD-SDI and DVB-ASI applications. In addition to serializing the input data stream, the GS9092 performs NRZI-to-NRZ encoding and scrambling as per SMPTE 259M-C when operating in SMPTE mode. When operating in DVB-ASI mode, the device will insert K28.5 sync characters and 8b/10b encode the data prior to serialization.

Key Features
• SMPTE 259M-C compliant scrambling and NRZI to NRZ encoding (with bypass)
• DVB-ASI sync word insertion and 8b/10b encoding
• Integrated Cable Driver
• Integrated line-based FIFO for data alignment/delay, clock phase interchange, DVB-ASI data packet insertion, and ancillary data packet insertion
• User selectable additional processing features including:
• ANC data checksum, and line number calculation and insertion
• TRS and EDH packet generation and insertion
• illegal code remapping
• Enhanced Gennum Serial Peripheral Interface (GSPI)
• JTAG test interface
• +1.8V internal cable driver and core power supply
• Optional +1.8V or +3.3V digital I/O power supply
• Small footprint (8mm x 8mm)
• Low power operation (typically 170mW)
• Pb-free and RoHS compliant

Applications
• SMPTE 259M-C Serial Digital Interfaces
• DVB-ASI Serial Digital Interfaces
