M02044CG-31

Overview

The M02044CG-31 is a high-gain limiting amplifier designed for data rates from 100 Mbps to 622 Mbps. It features PECL outputs and operates on either a 3.3V or 5V supply. The device includes an internal DC offset cancellation circuit, a programmable signal-level detector with hysteresis, and CMOS status outputs. It provides full output swing at minimum input sensitivity and supports an output jam function for squelch control.

Feature Summary

• Pin-compatible with the MC2044C for simplified board layout reuse
• Integrated on-chip DC offset cancellation loop requiring no external components
• Programmable signal-level detection with adjustable threshold settings
• Dual voltage operation capability supporting both 3.3V and 5V power supplies

Applications

• 622 Mbps SDH/SONET systems
• 100 Mbps Ethernet receivers
• SDH/SONET 155 Mbps transceivers
• FTTx and media converters
• Fast Ethernet receivers

Procurement Notes

Verify that the specific suffix CG-31 corresponds to the 16-pin QSOP package variant rather than the BCC package. Confirm RoHS compliance status via official manufacturer documentation as indicated by the G designator. Ensure the operating temperature range requirements align with the specified -40 °C to 85 °C industrial grade limits before finalizing procurement orders.

Selection Notes

Select this component when a direct replacement for the MC2044C is required within existing hardware footprints. Choose this part if the application demands low power consumption under 200 mW at 3.3V. It is suitable for designs needing integrated loss-of-signal detection without additional external comparator circuits. Consider the PECL output interface compatibility with downstream clock data recovery units.

Part Context

This device belongs to the M02044 series of limiting amplifiers manufactured by Mindspeed Technologies. It serves as a specialized receiver front-end solution for optical communication networks. The product line addresses high-speed serial data recovery needs in telecommunications infrastructure equipment.

Replacement Considerations

The M02044CG-31 is pin-compatible with the MC2044C. Other available solutions include the M02046-15, M02040-15, M02050-15, M02049-15, and M02043-15 for higher speed applications.
