MAX3385ECWN

Overview

The MAX3385ECWN is a high-speed serial deserializer manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 3V to 3.6V supply and supports data rates up to 2.488Gbps, compliant with SDH/SONET standards. The device accepts one PECL input and provides sixteen LVDS outputs. Packaged in a 64-pin TQFP, it functions within an industrial temperature range of -40°C to +85°C. Key electrical specifications include a maximum power dissipation of 1W and a typical operating current of 200mA.

Feature Summary

• Converts high-speed serial PECL signals into parallel LVDS outputs for system interfacing
• Supports SDH/SONET network synchronization and transmission protocols
• Provides robust electrostatic discharge protection for reliable operation

Applications

• SDH/SONET network infrastructure equipment
• High-speed digital signal processing interfaces
• Telecommunications base station hardware

Procurement Notes

Verify the specific suffix ECWN against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status as legacy variants may differ. Check manufacturer lifecycle status for availability and long-term supply commitments before integration.

Selection Notes

Select this component when a single PECL source must drive multiple LVDS loads at OC-48 speeds. Ensure the PCB layout accommodates the 64-pin TQFP footprint. Verify that the system power budget supports the 200mA operating current requirement under worst-case thermal conditions.

Part Context

This part belongs to the MAX3885 family of serializers and deserializers designed for optical networking applications. It serves as the receiver counterpart to serializers like the MAX3884, enabling complete serial-to-parallel conversion chains for SONET/SDH systems requiring low jitter performance.

Replacement Considerations

The MAX3885ECB+ is a pin-compatible alternative offering similar functionality. Verify that the replacement matches the required temperature range and packaging format for direct board substitution.
