DS125BR111RTWR

Overview

The DS125BR111RTWR is a dual-channel ultra-low power signal repeater manufactured by Texas Instruments. It supports data rates up to 12.5 Gbps with a maximum clock frequency of 6 GHz. The device operates on a single supply voltage ranging from 2.375 V to 3.6 V, typically 2.5 V or 3.3 V, with a typical operating current of 52 mA. It features AC-coupled CML inputs and outputs, ensuring signal integrity across various interfaces. Key electrical parameters include a propagation delay of 70 ps and an input capacitance of 5 pF. The component is housed in a WQFN-24 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption design suitable for energy-efficient high-speed applications
• Dual-channel architecture providing independent signal regeneration for two lanes
• AC-coupled CML input and output stages for direct interface compatibility

Applications

• Front port interconnects in networking equipment
• Backplane signal extension in server architectures
• Peripheral I/O signal buffering for high-speed peripherals

Procurement Notes

Verify the specific suffix RTWR confirms the reel packaging format and tape width required for automated assembly processes. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to PCB layout and reflow soldering profile selection. Ensure the ordering quantity matches the standard factory reel size to avoid cut-tape handling requirements.

Selection Notes

Select this component when a dual-channel solution is required for signals up to 12.5 Gbps with strict power constraints. Compare against the DS125DF111 if retiming functionality with embedded clock recovery is needed instead of simple repeating. Verify that the WQFN-24 package footprint aligns with the available board space and thermal management capabilities of the target system.

Part Context

This part belongs to the DS125BR111 series of signal buffers and repeaters from Texas Instruments. It is distinct from the DS125DF111, which is a retimer, and the DS125BR401, which offers four channels. The RTWR suffix specifically denotes the reel packaging variant used for surface-mount technology assembly lines.

Replacement Considerations

The DS125BR111RTWT is the tape-and-reel alternative with identical electrical characteristics but different packaging form factor. For multi-lane requirements, the DS125BR401 provides a quad-channel option. No third-party pin-compatible substitutes are publicly confirmed.
