DS125MB203SQE/NOPB

Overview

The DS125MB203SQE/NOPB is a dual-port multiplexer and fanout buffer designed for high-speed serial data transmission. It supports data rates up to 12.5 Gbps with CML input and output interfaces. The device operates within a supply voltage range of 2.375V to 3.6V and functions reliably across an industrial temperature range of -40°C to +85°C. Packaged in a 54-pin WQFN (10x5.5mm) surface-mount footprint, it draws approximately 160mA of operating current. This component integrates signal conditioning capabilities suitable for demanding interconnect applications requiring low latency and high signal integrity.

Feature Summary

• Dual-port architecture supporting simultaneous signal routing and distribution
• Integrated adaptive equalization to compensate for channel loss
• Configurable via I2C interface for flexible system integration

Applications

• High-performance computing systems
• Data center interconnects
• Storage area networks

Procurement Notes

Verify the specific suffix 'SQE' against official Texas Instruments documentation to confirm package variant and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 54-WQFN form factor. Confirm that the design supports the required 12.5 Gbps signaling standards before finalizing procurement orders.

Selection Notes

Select this component when a dual-port mux/fanout solution is required for 12.5 Gbps links. Compare power consumption metrics against alternative buffers if thermal management is critical. Verify that the CML I/O levels match the source and destination devices in the target circuit design.

Part Context

This part belongs to the DS125MB203 series of LVDS interface ICs manufactured by Texas Instruments. It serves as a signal conditioning element within high-speed digital communication chains. The device complements other retimers and redrivers in the portfolio by providing multiplexing and buffering functions without full retiming capabilities.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives. Verify electrical parameter equivalence for any cross-reference candidates.
