JAJSBK7H January 2012 – February 2018 DS125DF410
The DS125DF410 is a multi-rate, 4-channel retimer. Each channel in the DS125DF410 operates independently. All channels include a Continuous Time Linear Equalizer (CTLE), Decision Feedback Equalizer (DFE), Clock and Data Recovery circuit (CDR) and a differential driver with programmable output voltage and de-emphasis. Each channel also has its own Eye Opening Monitor (EOM) and configurable Pseudo-Random Bit Sequence (PRBS) pattern generator that can be used for debug purposes.
The DS125DF410 is configurable through a single SMBus port. The DS125DF410 can also act as an SMBus master to configure itself from an EEPROM.
