Overview
The DS125BR111RTWT is a dual-channel ultra-low power repeater manufactured by Texas Instruments, designed for high-speed serial data transmission. It supports data rates up to 12.5 Gbps with a maximum clock frequency of 6 GHz. The device features AC-coupled CML input and output types, ensuring signal integrity across various interfaces. Key electrical parameters include a propagation delay of 70 ps and an operating supply voltage range from 2.375 V to 3.6 V, typically powered at 2.5 V or 3.3 V. It draws 52 mA during operation and includes an I2C interface for configuration. The component operates within a temperature range of -40°C to +85°C and is housed in a WQFN-24 package.
Feature Summary
- Ultra-low power consumption design suitable for energy-efficient applications
- Dual-channel architecture supporting high-speed serial data retransmission
- Integrated I2C interface for flexible device configuration and control
Applications
- Front port interconnects
- Backplane connections

Procurement Notes
Verify the specific suffix RTWT against official datasheets to confirm tape-and-reel packaging details. Ensure compatibility with required voltage levels and thermal management specifications for the target environment. Cross-reference part numbers with manufacturer documentation to avoid confusion with similar variants like RTWR.
Selection Notes
Select this component when dual-channel signal regeneration is required for speeds up to 12.5 Gbps. Consider the WQFN-24 package size for space-constrained designs. Verify that the system power supply aligns with the 2.375 V to 3.6 V operating range and that thermal dissipation meets the 52 mA current draw requirements.
Part Context
This part belongs to the DS125BR111 series of signal buffers and repeaters from Texas Instruments. It is engineered for high-performance interface applications requiring low latency and minimal power usage. The series is commonly used in networking and storage equipment where signal integrity over long traces is critical.
Replacement Considerations
Check for direct pin-to-pin replacements within the same family, such as DS125BR111RTWR, ensuring identical electrical characteristics and package dimensions. Verify functional equivalence before substitution.
