DS250DF230RTVT

Specialized Overview

The DS250DF230RTVT is a dual-channel multi-rate retimer from Texas Instruments, housed in a 32-pin WQFN package. It supports data rates ranging from 19.6 Gbps to 25.8 Gbps, including sub-rates such as 12.16512 Gbps and 9.8304 Gbps. The device operates on a single power supply of 2.5 V (±5%), with an operating temperature range of -40°C to +85°C. Key electrical specifications include a typical input-to-output latency of 175 ps without crosspoint and a total active mode supply current of 271 mA when all equalization features are enabled.

Specialized Feature Summary

• Dual-channel architecture with independent channel locking for flexible signal conditioning
• Integrated adaptive continuous-time linear equalizer (CTLE) and decision feedback equalizer (DFE)
• Low-jitter transmitter featuring a 3-tap finite impulse response (FIR) filter
• On-chip eye-opening monitor and PRBS pattern checker for system diagnostics

Specialized Applications

• Backplane and mid-plane reach extension
• Active cable assemblies
• Jitter cleaning for front-port optical interfaces in wireless and wired systems

Specialized Procurement Notes

Verify the specific RTVT suffix indicates the QFN-32 package and reel tape-and-reel shipping configuration. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the ordering documentation matches the exact part number to avoid discrepancies in package type or thermal characteristics during procurement.

Specialized Selection Notes

Select this model when improved thermal performance is required compared to the NFBGA variant, as the QFN package supports PCB temperatures up to 105°C without a heat sink. Verify that the design accommodates the 32-pin footprint and utilizes the exposed thermal pad for effective heat dissipation. Ensure the system power supply strictly adheres to the 2.5 V ±5% specification for optimal operation.

Specialized Part Context

This component belongs to the DS250DF230 family of high-speed serial link retimers. It serves as the QFN-packaged alternative to the DS250DF230ZLS, offering identical functional performance with enhanced thermal management capabilities. The RTVT suffix specifically denotes the reel packaging format for surface-mount assembly.

Specialized Replacement Considerations

The DS250DF230ZLS is the primary pin-compatible alternative within the same family, differing primarily in package type and thermal characteristics. No other direct substitutes are documented in the official datasheet.
