DS250DF410 25 Gbps Multi-Rate 4-Channel Retimer
1 Features
- 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 25.78125-Gbps 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 supporting 35+ dB channel loss at 12.9 GHz
- Adjustable transmit amplitude: 205 mVppd to 1225 mVppd (Typical)
- On-chip eye opening monitor (EOM), PRBS pattern checker/generator
- Supports JTAG/AC-JTAG boundary scan
- Small 6-mm × 6-mm BGA package with easy flow-through routing
2 Applications
