DS250DF230ZLSR

Specialized Overview

The DS250DF230ZLSR is a multi-rate retimer manufactured by Texas Instruments, designed for high-speed serial data transmission. It features two independent channels capable of operating at data rates up to 25.8 Gbps. The device operates within a supply voltage range of 2.375 V to 2.625 V and supports a propagation delay of 140 ps. It is housed in a WQFN-32 package suitable for surface mount technology. The component functions as a signal buffer and repeater, intended for use in backplane, front port, and active cable applications.

Specialized Feature Summary

• Multi-rate retimer architecture supporting flexible data rate configurations
• Dual-channel design with differential RX inputs and TX outputs
• Integrated mux functionality for signal conditioning

Specialized Applications

• Backplane interconnects
• Front port connections
• Active cables

Specialized Procurement Notes

Verify the specific suffix ZLSR against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the WQFN-32 form factor. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Cross-reference ordering information with authorized distributors to validate current availability status.

Specialized Selection Notes

Select this component when dual-channel retiming is required for 25G Ethernet or similar high-speed interfaces. Consider the WQFN-32 package constraints for board space. Evaluate power consumption requirements against the specified operating current. Compare performance metrics such as jitter attenuation against alternative retimers if signal integrity is critical.

Specialized Part Context

This part belongs to the DS250DF230 series of retimers from Texas Instruments. It shares functional similarities with other devices in the family but differs in packaging and specific electrical characteristics. The ZLSR suffix indicates a specific reel-based configuration distinct from other variants like the RTVR.

Specialized Replacement Considerations

The DS250DF230RTVR is a documented variant within the same product family. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure that any replacement maintains the required 25.8 Gbps data rate capability.
