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

• Low power operation (typically 200mW)
• Pb-free and RoHS compliant
Applications
• SMPTE 259M-C Serial Digital Interfaces
• DVB-ASI Serial Digital Interfaces
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.
Parallel data inputs are provided for 10-bit multiplexed
formats at SD signal rates. A 27MHz parallel clock input
signal is also required.
The integrated cable driver 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 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).
