25-Gbps enhanced multi-rate 2-channel retimer

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.
