GS9001-CQME3

Specialized ICS Overview

The GS9001-CQME3 is an Error Detection and Handling (EDH) coprocessor compliant with SMPTE RP165. It supports 4ƒsc NTSC, 4ƒsc PAL, and 4:2:2 component standards up to 18 MHz luminance sampling. The device operates at a maximum clock frequency of 40 MHz with data rates up to 40 Mb/s. Powered by a single 5V supply, it consumes approximately 85 mA typical current. Key functions include EDH insertion/extraction, CRC calculation using the CCITT polynomial, automatic standard detection, and ancillary data verification. It features a 21-bit errored field counter and provides timing signals including horizontal sync, vertical blanking, and field ID.

Specialized ICS Procurement Notes

Verify that the E3 suffix confirms lead-free and green status. Confirm the package is 44-PQFP. Check if the device meets specific temperature requirements as the range is 0°C to 70°C. Ensure the design does not require new development support as the part is not recommended for new designs.

Specialized ICS Selection Notes

Select this component for systems requiring SMPTE RP165 compliance. Ensure the system uses parallel digital video interfaces compatible with the 8-bit or 10-bit input/output. Verify that a 5V power supply is available. Consider the 40 MHz operating speed limit when designing clock circuits.

Specialized ICS Part Context

The GS9001 is part of the Genlinx family of digital video processing ICs manufactured by Semtech Corporation (formerly Gennum). It serves as a specialized coprocessor for handling error detection and timing in serial digital interfaces. The CQM variant denotes the commercial temperature range and PQFP package.
