GS1559-CBE2

Video Processing Overview

The GS1559-CBE2 is a multi-rate deserializer featuring an integrated reclocker and serial loop-through cable driver. It supports SMPTE 292M, SMPTE 259M-C, and DVB-ASI standards with automatic configuration for HD-SDI and SD-SDI. The device includes dual serial digital input buffers with a 2x1 multiplexer, NRZI to NRZ decoding, descrambling, and word alignment. It provides a 20-bit or 10-bit parallel output bus operating at rates up to 148.5 MHz. Power supplies include a 1.8V core and 3.3V charge pump/digital I/O.

Video Processing Feature Summary

• Integrated reclocker with wide jitter tolerance and rapid lock time
• Serial loop-through cable driver with selectable reclocked or buffered output
• Automatic standards detection for SMPTE and DVB-ASI modes
• Comprehensive error detection and correction capabilities including EDH and CRC

Video Processing Applications

• SMPTE 292M Serial Digital Interfaces
• SMPTE 259M-C Serial Digital Interfaces
• DVB-ASI Serial Digital Interfaces

Video Processing Procurement Notes

Verify the specific suffix 'CBE2' against official Gennum/Semtech documentation to confirm package type and temperature range. Ensure compatibility with external VCO components like the GO1555 as recommended in datasheet revisions. Confirm RoHS compliance status for the specific manufacturing lot.

Video Processing Selection Notes

Select this component when a receive solution for HD-SDI, SD-SDI, or DVB-ASI is required alongside signal loop-through. It is suitable for designs needing integrated descrambling, word alignment, and error correction without external processing. Consider the 11mm x 11mm footprint and power supply requirements during PCB layout.

Video Processing Part Context

Originally manufactured by Gennum Corporation, this part was acquired by Semtech Corporation. The GS1559 belongs to the HD-LINX II family of serializers and deserializers designed for professional video applications. It serves as a key component in signal distribution and conversion chains within broadcast infrastructure.
