DS125MB203SQ/NOPB

Overview

The DS125MB203SQ/NOPB is an LVDS interface integrated circuit manufactured by Texas Instruments, functioning as a dual-port multiplexer and fanout buffer. It supports data rates up to 12.5 Gb/s with CML input and output types. The device operates within a temperature range of -40°C to +85°C and utilizes a WQFN-54 surface-mount package. It draws a typical operating supply current of 160 mA and features humidity sensitivity classification.

Feature Summary

• Dual-port architecture enabling simultaneous signal routing and distribution
• Integrated fanout buffering capability for signal integrity maintenance
• Configurable via SMBus slave mode for flexible system integration

Applications

• SFP+ optical module transceiver interfaces
• FPGA interconnection systems requiring signal splitting
• High-speed serial link multiplexing applications

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm package type and operational specifications. Ensure compliance with RoHS directives and moisture sensitivity levels prior to assembly. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when dual-port mux and fanout functionality is required at 12.5 Gb/s speeds. Consider the WQFN-54 package constraints for PCB layout. Evaluate thermal management requirements given the 160 mA operating current draw in high-density designs.

Part Context

This part belongs to the DS125MB203 series of high-speed interface ICs from Texas Instruments. It is designed for demanding data communication environments where signal distribution and switching are critical. The NOPB suffix indicates lead-free construction compliant with environmental standards.

Replacement Considerations

The DS100MB203 is a related model within the same family offering similar mux and buffer capabilities. Verify pin compatibility and electrical parameter alignment before substitution.
