• Includes integrated power detector with programmable LOS threshold
• Supports automatic squelch function during signal loss conditions

Applications

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

Procurement Notes

Verify the specific ordering suffix EEE+ against official documentation to confirm lead-free status and package type. Confirm availability through authorized distributors as stock levels fluctuate. Ensure environmental compliance matches project requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring pin compatibility with Mindspeed MC2045-2 postamplifiers. Consider its single-supply operation and low current consumption for power-sensitive designs. Verify input sensitivity and offset correction needs align with system specifications.

Part Context

This part belongs to the MAX3645 series of limiting amplifiers designed for high-speed optical and copper receivers. It integrates gain stages, offset correction, and loss-of-signal detection in a compact surface-mount package suitable for dense PCB layouts.

Replacement Considerations

Pin-compatible replacements include Mindspeed MC2045-2 and MC2045-2Y. Verify electrical parameters and pin assignments match before substitution.
