Description

The GS9090A is a 270Mb/s reclocking deserializer with an internal FIFO. When used in conjunction with one of Gennum’s SDI Cable Equalizers, a receive solution for SD-SDI and DVB-ASI applications can be realized.

Key Features

• SMPTE 259M-C compatible descrambling and NRZI to NRZ decoding (with bypass)

• 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

• Integrated VCO and reclocker

• Single serial digital input buffer with wide input sensitivity and common mode point

• User selectable additional processing features including:

♦ TRS, ANC data checksum, and EDH CRC error detection and correction

♦ 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)

• 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

• Small footprint (8mm x 8mm)

• Low power operation (typically 145mW)

• Pb-free and RoHS compliant

Applications

• SMPTE 259M-C Serial Digital Interfaces

• DVB-ASI Serial Digital Interfaces
