GS1531-CB

Video Processing Overview

The GS1531-CB is a multi-rate serializer with an integrated cable driver designed for SMPTE 292M, SMPTE 259M-C, and DVB-ASI standards. It supports parallel digital input buses of 20-bit or 10-bit width at frequencies up to 148.5MHz. The device features ClockCleaner™ technology to reject over 300ps of jitter on the input PCLK. Power supplies include a 1.8V core and a 3.3V charge pump/I/O supply. It provides NRZ to NRZI encoding, scrambling, and optional data processing functions such as EDH generation and TRS insertion.

Video Processing Procurement Notes

Verify the specific suffix 'CB' against the manufacturer's official ordering information to confirm package type and temperature range specifications. Ensure compatibility with required solder reflow profiles, distinguishing between lead-free and standard eutectic requirements based on the exact procurement variant.

Video Processing Selection Notes

Select this component when designing systems requiring compliance with SMPTE 292M/259M-C or DVB-ASI serial digital interface standards. It is suitable for applications needing robust jitter rejection via the internal PLL and integrated signal processing capabilities like EDH and TRS generation without external logic.

Video Processing Part Context

The GS1531 belongs to Gennum's HD-LINX II family of serializers. It is engineered to work in conjunction with voltage-controlled oscillators like the GO1555 to form complete transmit solutions for high-definition and standard-definition video transmission environments.

Video Processing Replacement Considerations

Consult official documentation for direct substitutes within the HD-LINX series. Verify pinout and electrical characteristics before considering alternative components.
