MAX3874AEGJ

Overview

The MAX3874AEGJ is a clock and data recovery (CDR) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. Designed for SONET/SDH and DWDM applications, it features a single circuit with CML and LVTTL inputs and outputs. The device supports a maximum frequency of 2.0212Gbps and operates on a 3V to 3.6V supply voltage. It includes an internal PLL and offers differential input/output capabilities. The component is housed in a 32-VFQFN exposed pad package (5x5 mm) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports SONET/SDH and DWDM standards with a maximum data rate of 2.0212Gbps
• Features both CML and LVTTL input/output interfaces
• Includes an internal Phase-Locked Loop (PLL)
• Operates on a 3V to 3.6V power supply

Applications

• SONET/SDH systems
• DWDM networks

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm pinout and electrical characteristics. Confirm availability status as lead times may vary. Ensure the 32-QFN package dimensions match the target PCB footprint requirements.

Selection Notes

Select this component for high-speed serial data recovery in optical communication links. Ensure the design accommodates the 3V to 3.6V supply range and the thermal requirements of the 32-QFN package. Verify compatibility with system-level CML or LVTTL signaling standards.

Part Context

This part belongs to the MAX3874 family of clock and data recovery ICs. It is distinct from other Maxim Integrated timing devices by its specific focus on SONET/SDH and DWDM protocols with mixed CML/LVTTL interface support.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX3874 series or compatible CDRs from Analog Devices that support the same 2.0212Gbps rate and 32-QFN package.
