GS9090B GenLINX® III 270Mb/s Deserializer for SDI

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 8b/10b decoding

Integrated line-based FIFO for data alignment/delay,

clock phase interchange, DVB-ASI data packet

extraction and clock rate interchange, and ancillary

data packet extraction

In addition to reclocking and deserializing the input data

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

scrambling as per SMPTE 259M-C, and word alignment

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.

•

Integrated VCO and reclocker

User selectable additional processing features

including:

The internal reclocker features a very wide input jitter tol-

erance, and is fully compatible with both SMPTE and

DVB-ASI input streams.

TRS, ANC data checksum, and EDH CRC error

detection and correction

programmable ANC data detection

illegal code remapping

The GS9090B includes a range of data processing

functions such as EDH support (error detection and han-

dling), and automatic standards detection. The device can

also detect and extract SMPTE 352M

payload identifier packets and independently identify the

received video standard. This information is read from in-

ternal registers via the host interface port.

•

Internal flywheel for noise immune H, V, F extraction

Automatic standards detection and indication

Enhanced Gennum Serial Peripheral Interface (GSPI)

JTAG test interface

Polarity insensitive for DVB-ASI and SMPTE signals

The GS9090B also incorporates a video line-based FIFO.

This FIFO may be used in four user-selectable modes to car-

ry out tasks such as data alignment / delay, clock phase in-

terchange, MPEG packet extraction and clock rate

interchange, and ancillary data packet extraction.

+1.8V core power supply with optional +1.8V or +3.3V

I/O power supply

•

Small footprint (8mm x 8mm)

Low power operation (typically 145mW)

Pb-free

Parallel data outputs are provided in 10-bit multiplexed

format, with the associated parallel clock output signal op-

erating at 27MHz.

Applications

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.

•

SMPTE 259M-C Serial Digital Interfaces

•

DVB-ASI Serial Digital Interfaces
