M02044CG-61

Overview

The M02044CG-61 is a high-gain limiting amplifier designed for data rates from 100 Mbps to 622 Mbps. It operates on a 3.3V or 5V supply and features PECL outputs. The device includes an internal DC offset cancellation circuit, a programmable signal-level detector with hysteresis, and CMOS Status and LOS outputs. It offers low power consumption of less than 200 mW at 3.3V and provides full output swing even at minimum input sensitivity.

Feature Summary

• Pin compatible with the MC2044C
• Operates with a 3.3V or 5V supply
• Programmable input-signal level detect
• On-chip DC offset cancellation circuit
• CMOS Signal Detect and LOS outputs
• Output Jam Function

Applications

• 622 Mbps SDH/SONET
• 100 Mbps Ethernet
• SDH/SONET 155 Mbps Transceivers
• FTTx and Media Converters
• Fast Ethernet Receivers

Procurement Notes

Verify that the specific suffix -61 corresponds to the BCC package type as indicated in the ordering information. Confirm RoHS compliance status via the 'G' designator in the part number. Ensure the operating temperature range meets the application requirements of -40 °C to 85 °C. Cross-reference pinout diagrams for the BCC package to ensure correct board layout compatibility.

Selection Notes

Select this component when a limiting amplifier supporting up to 622 Mbps is required. It is suitable for applications needing PECL outputs and integrated signal detection. Consider the M02044CG-31 if a QSOP package is preferred instead of the BCC package. Evaluate power consumption needs against the < 200 mW specification at 3.3V operation.

Part Context

This device belongs to the M02044 series of limiting amplifiers from Mindspeed Technologies. It serves as a direct replacement for the MC2044C in terms of footprint and functionality. Other variants in the family support higher data rates up to 4.3 Gbps, such as the M02049-15 and M02043-15, which utilize CML outputs instead of PECL.

Replacement Considerations

The M02044CG-31 is a pin-compatible alternative offering the same electrical characteristics but housed in a 16-pin QSOP package instead of the BCC package found in the M02044CG-61.
