GS9025ACQM

Overview

The GS9025ACQM is a serial digital receiver manufactured by Gennum Corporation, designed for high-performance clock and data recovery in serial digital signal applications. It supports SMPTE 259M compliance and operates at data rates up to 540Mb/s. The device accepts single-ended or differential serial digital inputs and outputs differential clock and retimed data signals at PECL levels with an amplitude of 800mV. Key electrical parameters include an on-board cable equalizer providing up to 40dB of gain at 200MHz, enabling equalization for over 350 meters of high-quality cable at 270Mb/s. It features auto-rate selection for five input data rates with manual override capability.

Feature Summary

• Provides automatic cable equalization and high-performance clock and data recovery for serial digital signals.
• Supports operation with both single-ended and differential serial digital data inputs.
• Features auto-rate selection for five input data rates with manual override functionality.

Applications

• Cable equalization and clock/data recovery for high-speed serial digital interface applications.
• Systems involving SMPTE 259M data standards.
• Video signal processing requiring automatic rate selection and equalization.

Procurement Notes

Verify the manufacturer designation as Gennum Corporation when sourcing this component. Confirm that the part number suffix CQM corresponds to the specific package and temperature grade required for your design. Ensure compatibility with existing system voltage requirements and signal levels before procurement.

Selection Notes

Select the GS9025ACQM for applications requiring SMPTE 259M compliance and automatic equalization for long cable runs. Consider the PECL output levels and the need for external VCO resistors for rate configuration. Evaluate if the 540Mb/s maximum data rate meets the specific bandwidth requirements of the target serial digital interface.

Part Context

The GS9025ACQM belongs to the GS9025A family of serial digital receivers from Gennum Corporation. This family includes variants such as GS9025ACTM and GS9025ACQME3, which share similar functional descriptions but may differ in package type or environmental specifications. The component is distinct from power management ICs like those listed under AMD Virtex US+ contexts.

Replacement Considerations

Direct replacements within the same family include GS9025ACQME3 and GS9025ACTM. Verify pinout compatibility and electrical characteristics before substituting. No cross-manufacturer equivalents are documented in the provided source material.
