DS250DF410 - Texas Instruments

DS250DF410 25 Gbps Multi-Rate 4-Channel Retimer

The DS250DF410 is a four-channel multi-rate retimer with integrated signal conditioning. It is used to extend the reach and robustness of long, lossy, crosstalk-impaired high-speed serial links while achieving a bit error rate (BER) of 10-15 or less. Each channel of the DS250DF410 independently locks to serial data rates in a continuous range from 20.2752 Gb.

Features

•1 Quad-channel multi-rate retimer with integrated signal conditioning
• All channels lock independently from 20.2752 to 25.8 Gbps (including sub-rates such as 10.3125 Gbps, 12.5 Gbps, and more)
• Ultra-low latency: <500 ps typical for 25.78125Gbps data rate
• Single power supply, no low-jitter reference clock required, and minimal supply decoupling to reduce board routing complexity and BOM cost
• Integrated 2×2 cross point
• Adaptive continuous time linear equalizer (CTLE)
• Adaptive decision feedback equalizer (DFE)
• Low-jitter transmitter with 3-Tap FIR filter
• Combined equalization supp.
