GS1559-CB

Video Processing Overview

The GS1559-CB is a multi-rate deserializer with an integrated loop-through cable driver, compliant with SMPTE 292M and SMPTE 259M-C standards. It supports HD-SDI, SD-SDI, and DVB-ASI serial digital interfaces. The device features automatic configuration for HD and SD modes, NRZI to NRZ decoding, descrambling, and word alignment. It includes dual serial digital input buffers with a 2x1 multiplexer, an integrated reclocker with wide jitter tolerance, and a selectable reclocked or non-reclocked serial output. Power supplies include 1.8V core and 3.3V charge pump/digital I/O.

Video Processing Procurement Notes

Verify the specific suffix 'CB' against official Gennum/Semtech ordering information 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 batch.

Video Processing Selection Notes

Select this component for applications requiring simultaneous reception of HD-SDI, SD-SDI, or DVB-ASI signals with loop-through distribution. Consider the integrated reclocker for jitter cleaning and the error correction features for signal integrity. Evaluate power supply requirements for 1.8V core and 3.3V I/O domains.

Video Processing Part Context

The GS1559 belongs to the HD-LINX II family of serial digital video processors. It is designed to work with automatic cable equalizers and voltage-controlled oscillators to form complete receive solutions for professional broadcast video infrastructure.

Video Processing Replacement Considerations

Check for updated Gennum or Semtech equivalents that may offer improved performance or availability. Verify pinout and register compatibility if substituting with other deserializers in the same product line.
