M02045-2Y06-T

Overview

The M02045-2Y06-T is a 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 features a typical input sensitivity of 1.6 mVpp. The device provides PECL compatible logic outputs and includes a programmable signal-level detector with approximately 2 dB optical hysteresis to prevent output chatter at low input levels. A JAM function disables the output when no valid signal is detected.

Feature Summary

• Integrated high gain limiting amplifier designed for fiber optic receivers
• Programmable signal-level detector with built-in hysteresis
• Complementary PECL data and signal detect logic outputs
• Output disable (JAM) function activates upon loss of valid signal

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 '06' corresponds specifically to the BCC++16L package type as listed in the official documentation. Confirm RoHS compliance status if required, noting that specific variants may carry a 'G' designation. Ensure the component source matches Mindspeed Technologies specifications before integration into designs requiring strict environmental ratings.

Selection Notes

Select this component for applications requiring a post-amplifier following a photodetector and transimpedance amplifier. It is suitable for systems needing PECL outputs and adjustable signal detection thresholds. Consider the BCC++16L package constraints and verify power supply requirements against the 3.3 V or 5 V operating conditions specified in the datasheet.

FAQ

How is the JAM function implemented?

The JAM function is implemented by externally connecting the ST output pin to the JAM input pin. This forces the data outputs to a fixed state when no valid signal level is present.

What is the purpose of the CAZ pins?

The CAZ+ and CAZ- pins are used for DC offset compensation. An external capacitor connected between these pins acts with internal feedback resistors to remove TIA output DC offset and internal device DC offset.
