MAX3645EEE+T

Overview

The MAX3645EEE+T is a limiting amplifier functioning as a data quantizer, operating from a single +2.97V to +5.5V supply over a -40°C to +85°C temperature range. It accepts wide input voltage ranges and provides constant-level positive emitter-coupled logic (PECL) outputs with controlled edge speeds. The device features an integrated power detector with complementary PECL loss-of-signal outputs indicating when input power drops below a programmable threshold. It operates at data rates between 125Mbps and 200Mbps with a typical supply current of 18mA.

Feature Summary

• Pin compatible with Mindspeed MC2045-2 and MC2045-2Y postamplifiers
• Integrated power detector with programmable loss-of-signal threshold
• Automatic squelch function holds data outputs static during signal loss
• Compatible with 4B/5B data coding standards

Applications

• SONET 155Mbps Transceivers
• Fast Ethernet Receivers
• FDDI 125Mbps Receivers
• FTTx Receivers
• ESCON Receivers

Procurement Notes

Verify the specific ordering suffix 'EEE+T' against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing board layouts designed for Mindspeed equivalents if applicable. Confirm lead-free status and RoHS compliance through manufacturer certificates prior to procurement.

Selection Notes

Select this component for applications requiring pin-compatible replacement of Mindspeed MC2045 series devices. Evaluate the need for programmable loss-of-signal detection and automatic squelch functionality. Consider the single-supply operation and PECL output requirements for system interface design.

Part Context

This part belongs to the MAX3645 family of limiting amplifiers designed for high-speed serial communication receivers. It serves as a data quantizer with integrated signal monitoring capabilities. The device is manufactured by Analog Devices under the Maxim Integrated brand, targeting optical and copper-based high-speed data links.

Replacement Considerations

The MAX3645EEE+T is explicitly documented as pin compatible with the Mindspeed MC2045-2 and MC2045-2Y postamplifiers. Verify electrical parameter alignment with these specific legacy parts before substitution.
