GS9090B GenLINX® III

270Mb/s Deserializer for SDI

GS9090B Data Sheet

Key Features

Description

•

SMPTE 259M-C compliant descrambling and NRZI

to NRZ decoding (with bypass)

The GS9090B is a 270Mb/s reclocking deserializer with

an internal FIFO. It provides a complete receive solution

for SD-SDI and DVB-ASI applications.

•

DVB-ASI sync word detection and 8b/10b decoding

Integrated line-based FIFO for data

In addition to reclocking and deserializing the input data

stream, the GS9090B performs NRZI-to-NRZ decoding,

descrambling as per SMPTE 259M-C, and word align-

ment when operating in SMPTE mode. When operating

in DVB-ASI mode, the device will word align the data to

K28.5 sync characters and 8b/10b decode the received

stream.

alignment/delay, clock phase interchange, DVB-ASI

data packet extraction and clock rate interchange,

and ancillary data packet extraction

•

Integrated VCO and reclocker

Automatic or manual selection between SMPTE

video and DVB-ASI data

The internal reclocker features a very wide input jitter

tolerance, and is fully compatible with both SMPTE and

DVB-ASI input streams.

•

User selectable additional processing features

including:

•

TRS, ANC data checksum, and EDH CRC error

detection and correction

The GS9090B includes a range of data processing

functions such as EDH support (error detection and

handling), and automatic standards detection. The de-

vice can also detect and extract SMPTE 352M

payload identifier packets and independently identify

the received video standard. This information is read

from internal registers via the host interface port.

•

programmable ANC data detection

illegal code remapping

•

Internal flywheel for noise immune H, V, F

extraction

•

Automatic standards detection and indication

Enhanced Gennum Serial Peripheral Interface

(GSPI)

The GS9090B also incorporates a video line-based

FIFO. This FIFO may be used in four user-selectable

modes to carry out tasks such as data alignment / delay,

clock phase interchange, MPEG packet extraction and

clock rate interchange, and ancillary data packet extrac-

tion.

•

JTAG test interface

Polarity insensitive for DVB-ASI and SMPTE

signals

•

+1.8V core power supply with optional +1.8V or

+3.3V I/O power supply

Parallel data outputs are provided in 10-bit multiplexed

format, with the associated parallel clock output signal

operating at 27MHz.

•

Small footprint (8mm x 8mm)

Low power operation (typically 145mW)

Pb-free

The device may also be used in a low-latency data pass

through mode where only descrambling and word align-

ment will be performed in SMPTE mode.

Applications

•

SMPTE 259M-C Serial Digital Interfaces
