M02045-2Y04-T

Overview

The M02045-2Y04-T is a high-gain limiting post-amplifier and quantizer designed for fiber optic communication applications up to 200 Mbps. It operates on a single 3.3 V or 5 V supply with a typical current consumption of 12.5 mA at 3.3 V. The device provides PECL-compatible differential data outputs and includes a programmable signal-level detector with approximately 2 dB optical hysteresis to prevent output chatter. It features an external JAM function to disable outputs when no valid signal is detected, ensuring noise immunity during loss-of-signal conditions.

Feature Summary

• Integrated high-gain limiting amplifier providing necessary gain for PECL compatible logic outputs following photodetector stages
• Programmable input signal level detector allowing user-defined thresholds for enabling logic outputs
• Built-in hysteresis in the signal detect function prevents output chatter at low input levels
• External JAM input function disables data outputs when no valid signal is present

Applications

• SDH/SONET 155 Mbps Transceivers
• Fast Ethernet Receivers
• FDDI 125 Mbps Receivers
• ESCON Receivers
• FTTx and Media Converters

Procurement Notes

Verify that the specific suffix '04' corresponds to the SOIC16 package variant as listed in the ordering information table. Confirm RoHS compliance status by checking for the 'G' designator if required, noting that standard parts may differ from RoHS-compliant versions. Ensure the operating temperature range matches the application requirements of -40 °C to 85 °C. Cross-reference the Mindspeed prefix 'M0' with the internal marking 'MC2045' to avoid identification errors during assembly.

Selection Notes

Select this component when a limiting amplifier with integrated signal detection is required for fiber optic receivers up to 200 Mbps. The device is suitable for replacing discrete amplifier solutions where space and power consumption are constraints. Consider the PECL output compatibility with downstream logic interfaces. Evaluate the need for the JAM function to manage noise during signal loss events. Verify that the input sensitivity and bandwidth meet the specific data rate and eye diagram requirements of the target protocol.

Part Context

This part belongs to the MC2045 family of post-amplifiers manufactured originally by Mindspeed Technologies, which has since been acquired by MACOM Technology Solutions. The family includes variants in different packages such as QSOP16, TSSOP20, and BCC++16L. The device serves as a critical interface between the transimpedance amplifier and the main data processing logic in optical communication systems.

Replacement Considerations

Direct substitutes include other MC2045 variants with different package suffixes (e.g., M02045-2Y03-T for QSOP16). RoHS-compliant versions are designated with a 'G' suffix (e.g., M02045G-2Y04-T). No alternative functional equivalents are documented in the provided source material.
