描述 Description

The GS9092A 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 GS9092A 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.
