M02049G-15

Overview

The M02049G-15 is a high-gain limiting amplifier from Mindspeed Technologies, designed for applications up to 6.144 Gbps. It features CML outputs and operates with either a 3.3V or 5V supply. The device includes rate select functionality for SFP applications and optimum sensitivity at data rates ≤ 1.25 Gbps. It incorporates two analog RSSI outputs proportional to average or peak-to-peak input signals, alongside a programmable signal-level detector. The component utilizes a 16-pin 3x3 mm QFN package.

Feature Summary

• Integrated DC offset cancellation circuit requiring no external components
• Programmable CML output amplitude level via external resistor
• Output jam function to disable data propagation during loss of signal
• Dual analog receive signal strength indicator (RSSI) outputs

Applications

• 2.5 Gbps STM-16/OC-48 SDH/SONET
• 1.06, 2.12 and 4.24 Gbps Fibre Channel
• 1.25 Gbps Ethernet
• CPRI data rates including 614.4, 1228.8, 2457.6, 3072.0, 4915.2 and 6144.0 Mbit/s

Procurement Notes

Verify the RoHS-compliant designation indicated by the 'G' suffix in the part number against current manufacturer documentation. Confirm that the Mindspeed Technologies datasheet remains the authoritative source for absolute maximum ratings and operating conditions. Ensure compatibility with the specified 16-pin 3x3 mm QFN package dimensions during integration.

Selection Notes

Select this component for high-speed optical receiver front-ends requiring limiting amplification up to 6.144 Gbps. Consider the integrated RSSI and LOS functions if system monitoring is required without additional discrete logic. Evaluate the power consumption implications when adjusting the CML output swing using the AMPSET pin resistor.

Part Context

This device belongs to the M02049-15 series of limiting amplifiers manufactured by Mindspeed Technologies. The M02049G-15 variant specifically denotes compliance with RoHS standards. It shares pin compatibility with the standard M02049-15 but includes the environmental compliance designation. Related solutions include the M02050-15 and M02040-15, which offer PECL outputs for lower speed applications.

Replacement Considerations

The M02043-15 is a confirmed pin-compatible substitute offering identical performance characteristics but lacks the rate select function. Verify functional requirements regarding bandwidth selection before substituting.
