DS250DF230
- Dual-channel multi-rate retimer with integrated signal conditioning
- All channels lock independently from 19.6 to 25.8 Gbps (including sub-rates, such as 12.16512 Gbps, 9.8304 Gbps, 6.144 Gbps, and more)
- Ultra-low latency: <500 ps Typical for 25.78125-Gbps data rate
- Adaptive continuous time linear equalizer (CTLE)
- Continuous adaptive decision feedback equalizer (DFE), capable of compensating large channel loss variation over temperature
- Combined equalization supporting 35-dB channel loss at 12.9 GHz
- On-chip eye-opening monitor (EOM), PRBS pattern checker and generator
- Low-jitter transmitter with 3-Tap FIR filter
- Integrated 2×2 cross-point
- Recovered clock available for system clock synchronization applications on channel 0
- Single power supply, no low-jitter reference clock required
- Wide stay-in-lock temperature range
The DS250DF230 is a dual-channel multi-rate retimer with integrated signal conditioning. The device is used to extend the reach and robustness of long, lossy, crosstalk-impaired high-speed serial links and while achieving a bit error rate (BER) of 10–15 or less.
Each channel of the DS250DF230 independently locks to serial data rates in a continuous range from 19.6 Gbps to 25.8 Gbps or to any supported sub-rate (÷2 and ÷4), including key data rates such as 12.16512 Gbps, 9.8304 Gbps, and 6.144 Gbps.
The DS250DF230 is offered in two package options, 36-pin NFBGA and 32-pin QFN, with compact body sizes of 5 × 5 mm. The NFBGA (ZLS) package offers robust performance and ease of design with minimal BOM footprint, while the QFN (RTV) package offers similar performance characteristics with improved thermal performance supporting PCB temperatures up to 105°C without the need for a heat sink.
