GS9092A

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 GS9092A will insert K28.5 sync characters and 8b/10b encode the data prior to serialization.

Parallel data inputs of GS9092A are provided for 10-bit multiplexed formats at SD signal rates. A 27MHz parallel clock input signal is also required.

The integrated cable driver of GS9092A features an adjustable signal swing and common mode operating point offering fully compliant SMPTE 259M-C cable driver connectivity.

The GS9092A includes a range of data processing functions such as automatic standards detection and EDH support. The device can also insert TRS signals, re-map illegal code words, and generate and insert SMPTE 352M payload identifier packets. All processing features are optional and may be enabled/disabled via external control pin(s) and/or host interface programming.

The GS9092A also incorporates a video line-based FIFO. This FIFO may be used in four user-selectable modes to carry out tasks such as data delay, clock phase interchange, MPEG packet insertion and clock rate interchange, and ancillary data packet insertion.

The GS9092A 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).
