GS9090-CNE3

Overview

The GS9090-CNE3 is a GenLINX-R III 270Mb/s reclocking deserializer designed for SDI and DVB-ASI applications. It features an internal FIFO, integrated VCO, and automatic standards detection. The device supports SMPTE 259M-C descrambling and NRZI to NRZ decoding, alongside DVB-ASI sync word detection and 8b/10b decoding. It operates from a +1.8V core supply with optional +1.8V or +3.3V I/O supplies, consuming typically 145mW. Packaged in a small 8mm x 8mm footprint, it includes enhanced SPI and JTAG interfaces.

Feature Summary

• Integrated line-based FIFO for data alignment, clock phase interchange, and ancillary data packet extraction
• Automatic or manual selection between SMPTE video and DVB-ASI data formats
• User-selectable error detection and correction including TRS, ANC data checksum, and EDH CRC
• Internal flywheel mechanism for noise-immune horizontal, vertical, and frame signal extraction

Applications

• SMPTE 259M-C Serial Digital Interfaces
• DVB-ASI Serial Digital Interfaces

Procurement Notes

Verify the specific suffix 'CNE3' against official Gennum documentation to confirm RoHS compliance and lead-free status. Ensure the component matches the 8mm x 8mm package dimensions and voltage requirements specified in the datasheet before integration into the design.

Selection Notes

Select this component when a low-power, high-performance deserializer is required for SD-SDI or DVB-ASI signals up to 270Mb/s. Consider its integrated reclocking and FIFO capabilities if cable equalization is handled by a separate upstream component. Verify compatibility with existing system power supplies regarding the +1.8V core and optional I/O voltages.

Part Context

The GS9090 belongs to the Gennum GenLINX-R III family of serial digital receivers. It is designed to work in conjunction with SDI Cable Equalizers to form a complete receive solution. The device provides advanced processing features such as automatic standards detection and enhanced serial peripheral interface control for flexible system integration.
