GS1561-CFTE3

Video Processing Overview

The GS1561-CFTE3 is a dual-rate deserializer compliant with SMPTE 292M and SMPTE 259M-C standards. It features auto-configuration for HD-SDI and SD-SDI signals, supporting NRZI to NRZ decoding and descrambling. The device includes DVB-ASI 8b/10b decoding capabilities and an integrated reclocker with wide jitter tolerance. It provides automatic or manual rate selection, error detection and correction for CRC, TRS, ANC, and EDH data, and supports illegal code remapping. The component utilizes a 1.8V core supply and 3.3V I/O supply.

Video Processing Feature Summary

• Dual serial digital input buffers with 2x1 multiplexer and integrated signal termination
• Integrated reclocker with wide input jitter tolerance and rapid asynchronous lock time
• Comprehensive data processing including error detection, correction, and ancillary data checksum verification
• Automatic standards detection and indication for HD-SDI, SD-SDI, and DVB-ASI modes

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 CFTE3 against official Gennum/Semtech ordering information to confirm package type and tape/reel specifications. Ensure compatibility with existing host interface configurations and power supply requirements (1.8V core, 3.3V I/O). Confirm RoHS compliance status for the specific manufacturing batch.

Video Processing Selection Notes

Select the GS1561-CFTE3 when a dual-rate deserializer without a loop-through cable driver is required. Unlike the GS1560A, this variant lacks the serial loop-through output stage. It is suitable for applications requiring HD-SDI and SD-SDI reception with integrated reclocking and extensive data integrity processing via the GSPI host interface.

Video Processing Part Context

The GS1561 is part of the HD-LINX II family of dual-rate serializers and deserializers. It is designed to work in conjunction with automatic cable equalizers like the GS1524. The component shares pinouts and functionality with the GS1560A, differing primarily in the absence of the integrated cable driver found in the GS1560A variant.

Video Processing Replacement Considerations

The GS1560A is a compatible alternative if a serial loop-through cable driver is needed. Verify that the replacement supports the required voltage levels and host interface protocols.
