GS9021ACFUE3

Specialized ICS Overview

The GS9021ACFUE3 is an Error Detection and Handling (EDH) coprocessor manufactured by Semtech Corporation, originally designed by Gennum. It implements EDH processing according to SMPTE RP-165 standards for serial digital video interfaces. The device supports parallel digital video inputs and outputs with a maximum operating frequency of 54 MHz. It provides automatic standard detection for NTSC and PAL formats, including 4:2:2 and 4:4:4:4 component standards. Key features include EDH insertion and extraction, noise-immune flywheel synchronization for timing signals, and configurable host interfaces via I²C or 8-bit parallel port.

Specialized ICS Feature Summary

• SMPTE RP-165 compliant EDH insertion and extraction for composite and component video standards.
• Noise-immune flywheel synchronization generating accurate horizontal, vertical, and field timing signals.
• Automatic detection of incoming video standards (NTSC/PAL, 4:2:2, 4:4:4:4) with manual override capability.
• Configurable host interface supporting both I²C serial and 8-bit parallel modes for control and status access.

Specialized ICS Applications

• EDH processing for SMPTE 259M serial digital interfaces in source equipment.
• Destination and distribution equipment requiring error flag extraction and correction.
• General purpose TRS formatted blank video stream generators with EDH capabilities.

Specialized ICS Procurement Notes

Verify the manufacturer origin, as the datasheet identifies Gennum Corporation as the original designer while the SKU lists Semtech Corporation. Confirm the package type is 64-LQFP (14x14 mm) and check the temperature range specification against the specific ordering suffix if available. Ensure compatibility with existing 5V logic levels and interface requirements.

Specialized ICS Selection Notes

Select this component for applications requiring strict SMPTE RP-165 compliance in SDI signal chains. It serves as a drop-in replacement for the GS9021. Consider the 54 MHz maximum clock frequency when designing for higher bandwidth standards. The device requires a 5.0V supply voltage and supports both 8-bit and 10-bit data paths.

Specialized ICS Part Context

The GS9021A is part of the Genlinx II family of serial digital video processors. It is primarily used on the transmit end of SDI interfaces, interfacing with encoders like the GS9002, GS9022, or GS9032. The device ensures signal integrity by handling error flags and correcting timing discrepancies in the video stream.

Specialized ICS Replacement Considerations

The datasheet explicitly states the GS9021A is a drop-in replacement for the GS9021. Verify pinout and electrical characteristics compatibility before substituting other EDH processors.
