Description
The GS9090 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 compliant descrambling and NRZI to NRZ decoding (with bypass)
• DVB-ASI sync word detection and 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
• Automatic or manual selection between SMPTE video and DVB-ASI data
• Single serial digital input buffer with wide input sensitivity
• 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
