DS560DF410 Four-Channel Multi-Rate Retimer

Texas Instruments DS560DF410 Four-Channel Multi-Rate Retimer comes with integrated signal conditioning. The device extends the reach and robustness of long, lossy, crosstalk-impaired high-speed serial links. Each channel in the DS560DF410 independently locks to symbol rates (PAM4 and NRZ) in a continuous range from 19.6 to 28.9GBd or any supported sub-rate. The integrated CDR function is ideal for front-port optical module applications to retime the high-speed serial data and reset the jitter budget. These features allow for individual lane forward error correction (FEC) pass-through. In addition, the DS560DF410 supports automatic lane rate switching for CDR lock up to five different combinations of modulation types and baud rates without host intervention.
