MAX3885ECB+

Serializers, Deserializers Overview

The MAX3885ECB+ is a deserializer designed for SDH/SONET applications, converting 2.488Gbps serial data to 16-bit wide, 155Mbps parallel data. It operates from a single +3.3V supply and accepts PECL serial clock and data inputs while delivering LVDS clock and data outputs. The device includes LVDS synchronization inputs for data realignment and reframing. It functions within an extended temperature range of -40°C to +85°C and is housed in a 64-pin TQFP package.

Serializers, Deserializers Feature Summary

• Converts high-speed serial data to parallel format suitable for SDH/SONET systems
• Features self-biasing PECL inputs that simplify AC coupling requirements
• Provides LVDS outputs and synchronization inputs for interfacing with high-speed digital circuitry

Serializers, Deserializers Applications

• 2.488Gbps SDH/SONET Transmission Systems
• Add/Drop Multiplexers
• Digital Cross Connects

Serializers, Deserializers Procurement Notes

Verify the component matches the specific lead-free designation indicated by the plus suffix. Confirm the package type corresponds to the 64-pin TQFP form factor required for the target design. Ensure the operating temperature range meets the environmental specifications of the intended deployment scenario before finalizing procurement.

Serializers, Deserializers Selection Notes

Select this component when a 1:16 deserialization ratio is required for SDH/SONET protocols. Ensure the system provides a stable +3.3V supply and compatible PECL input signaling. Verify that the downstream logic supports LVDS interfaces for both clock and data lines to maintain signal integrity at the specified data rates.

Serializers, Deserializers Part Context

This part belongs to the MAX3885 series of serializers and deserializers manufactured by Maxim Integrated. It serves as the deserialization counterpart to the MAX3875 serializer, facilitating complete serial-to-parallel and parallel-to-serial data conversion links in telecommunications infrastructure equipment.

Serializers, Deserializers Replacement Considerations

The MAX3885ECB is the non-lead-free equivalent of the MAX3885ECB+. Both share identical electrical characteristics and pinouts. Verify that the lead-free variant is acceptable for the assembly process if environmental compliance is mandatory.
