DS250DF410 Description
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 Gbps to 25.8 Gbps or to any supported subrate (÷2 and ÷4),...
DS250DF410 Key Features
