GS9092A GenLINX® III 270Mb/s Serializer for SDI and DVB-ASI  
Key Features  
Description  
SMPTE 259M-C compliant scrambling and NRZI to NRZ  
encoding (with bypass)  
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.  
DVB-ASI sync word insertion and 8b/10b encoding  
Integrated Cable Driver  
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.  
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:  
Š
ANC data checksum, and line number calculation  
and insertion  
Parallel data inputs are provided for 10-bit multiplexed  
formats at SD signal rates. A 27MHz parallel clock input  
signal is also required.  
Š
Š
TRS and EDH packet generation and insertion  
illegal code remapping  
The integrated cable driver features an adjustable signal  
swing and common mode operating point offering fully  
compliant SMPTE 259M-C cable driver connectivity.  
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)  
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.  
Low power operation (typically 200mW)  
Pb-free and RoHS compliant  
Applications  
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.  
SMPTE 259M-C Serial Digital Interfaces  
DVB-ASI Serial Digital Interfaces  
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).
