GS1670-IBE3

Video Processing Overview

The GS1670-IBE3 is a multi-rate SDI receiver supporting SMPTE 292, SMPTE 259M-C, and DVB-ASI standards. It operates at data rates of 1.485 Gb/s, 1.485/1.001 Gb/s, and 270 Mb/s. The device integrates an audio de-embedder for eight channels of 48 kHz audio and includes comprehensive error detection and correction features. Parallel outputs are selectable as either 20-bit or 10-bit formats. Power supplies include a 1.2 V digital core, 1.2 V and 3.3 V analog supplies, and selectable 1.8 V or 3.3 V I/O power. It functions within a temperature range of -20°C to +85°C.

Video Processing Procurement Notes

Verify the specific ordering suffix against official Semtech documentation to confirm package type and environmental compliance. Confirm that the component meets all required operating voltage and temperature specifications for the target application environment before procurement.

Video Processing Selection Notes

Select this component when a multi-rate SDI receiver with integrated audio processing is required. Ensure the system design accommodates the necessary 1.2V, 3.3V, and selectable I/O power rails. Verify compatibility with the GSPI host interface for configuration and control requirements.

Video Processing Part Context

The GS1670-IBE3 belongs to Semtech's HD/SD SDI Receiver family. It is designed to receive serial digital video signals and perform complete SMPTE processing. The device reduces PCB footprint by integrating deserialization, reclocking, and audio extraction into a single 100-ball BGA package.

Video Processing Replacement Considerations

Consult the GS1670/GS1671 Errata document (number 53878) for known device limitations. Verify functional equivalence with other Semtech receivers such as the GS1660AIBE3 if pinout or feature sets differ.
