M02045G-2Y04-T

Overview

The M02045G-2Y04-T is a RoHS-compliant post-amplifier and quantizer manufactured by Mindspeed Technologies, intended for fiber optic communication applications up to 200 Mbps. It operates with a 3.3 V or 5 V supply and provides high gain limiting amplification following the photodetector and transimpedance amplifier stages. The device delivers PECL compatible logic outputs and includes a programmable signal-level detector with approximately 2 dB of optical hysteresis to prevent output chatter at low input levels. A JAM function allows the user to disable data outputs when no valid signal is detected.

Feature Summary

• Integrated high-gain limiting amplifier providing necessary gain for PECL compatible logic outputs
• Programmable signal-level detector with typical 2 dB optical hysteresis to prevent noise-induced chatter
• JAM function disables data outputs when no valid signal is present at the inputs
• RoHS compliant construction available in SOIC16 package

Applications

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

Procurement Notes

Verify that the ordering suffix '04' corresponds specifically to the SOIC16 package variant as listed in the official documentation. Confirm the 'G' designation indicates RoHS compliance status for the specific batch. Ensure the component source matches Mindspeed Technologies specifications, noting that current branding may reflect MACOM Technology Solutions due to corporate acquisitions. Cross-reference the datasheet revision H details for accurate pin definitions and electrical characteristics.

Selection Notes

Select this component for fiber optic receiver chains requiring post-amplification and quantization up to 200 Mbps. It is suitable for applications needing programmable signal detection thresholds and automatic output squelch via the JAM function. Consider the SOIC16 package form factor for PCB layout constraints. Verify compatibility with 3.3 V or 5 V supply rails and ensure proper AC or DC coupling termination techniques are applied for PECL outputs.

Part Context

This part belongs to the MC2045-2Y family of integrated post-amplifiers designed for high-speed fiber optic communications. Originally released by Mindspeed Technologies, the product line supports various data rates including 155 Mbps and Fast Ethernet speeds. The M02045G-2Y04-T specifically denotes the RoHS-compliant version housed in an SOIC16 package, operating within a temperature range of -40 °C to 85 °C.

Replacement Considerations

Consult the official ordering information for other package variants such as QSOP16 (suffix 03), TSSOP20 (suffix 01), or BCC++16L (suffix 06) if different footprint requirements exist. Non-RoHS versions are available without the 'G' designator. No direct cross-manufacturer substitutes are documented in the provided datasheet.
