GS9090ACNE3

Video Processing Overview

The GS9090ACNE3 is a 270Mb/s reclocking deserializer with an internal FIFO, designed for SD-SDI and DVB-ASI applications. It features SMPTE 259M-C compatible descrambling, NRZI to NRZ decoding, and DVB-ASI 8b/10b decoding. The device includes an integrated VCO, line-based FIFO for data alignment and packet extraction, and supports automatic standards detection. It operates on a +1.8V core supply with optional +1.8V or +3.3V I/O power supplies, typically consuming 145mW in a small 8mm x 8mm footprint.

Video Processing Feature Summary

• SMPTE 259M-C compliant descrambling and NRZI to NRZ decoding with bypass capability
• Integrated line-based FIFO supporting data alignment, clock phase interchange, and ancillary data packet extraction
• Automatic video standard detection and indication via enhanced Gennum Serial Peripheral Interface (GSPI)
• Error detection and correction capabilities including TRS, ANC data checksum, and EDH CRC

Video Processing Applications

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

Video Processing Procurement Notes

Verify the specific ordering suffix ACNE3 against manufacturer documentation to confirm package type and compliance status. Ensure compatibility with required I/O voltage levels (+1.8V or +3.3V) during system design. Confirm that the host interface configuration matches the intended GSPI or JTAG mode of operation as defined in the datasheet.

Video Processing Selection Notes

Select this component for systems requiring robust reclocking and deserialization of serial digital video streams. Consider its low power consumption and small footprint for space-constrained designs. Evaluate the need for its extensive error correction and ancillary data processing features against simpler deserializer alternatives if such functionality is not required by the application.

Video Processing Part Context
