Product Overview
The Texas Instruments DS250DF810 is a high-performance, 8-channel, multi-rate retimer designed to enhance signal integrity in high-speed serial communication systems. It integrates advanced signal conditioning, including adaptive Continuous Time Linear Equalization (CTLE) and Decision Feedback Equalization (DFE), to effectively compensate for channel losses and impairments.
This retimer is crucial for extending the reach and improving the robustness of long, lossy, and crosstalk-impaired serial links, ensuring reliable data transmission with a low bit error rate (BER).
Key Features
- Octal-channel, multi-rate retimer with integrated signal conditioning.
- Supports data rates from 20.2752 Gbps to 25.8 Gbps, including sub-rates.
- Features adaptive CTLE and DFE for comprehensive signal equalization.
- Ultra-low latency (<500 ps typical).
- Single power supply operation, reducing system complexity and BOM cost.
- Integrated 2x2 cross-point switch for flexible lane management.
- On-chip eye monitor, PRBS generator/checker for in-system diagnostics.
Primary Applications
- Backplane and mid-plane reach extension.
- Jitter cleaning for front-port optical modules.
- Enables compliance with standards such as IEEE802.3bj 100GbE, Infiniband EDR, and OIF-CEI-25G-LR/MR/SR/VSR electrical interfaces.
- Supports SFP28, QSFP28, CFP2/CFP4, and CDFP form factors.
