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
