3 Description
The DS560DF810 is an eight-channel multi-rate retimer with integrated signal conditioning. It extends the reach and robustness of long, lossy, crosstalk-impaired high-speed serial links.
Each channel in the DS560DF810 independently locks to symbol rates (PAM4 and NRZ) in a continuous range from 19.6 to 28.9 GBd or to any supported sub-rate. The integrated CDR function is an excellent choice for front-port optical module applications to reset the jitter budget and retime the high-speed serial data. These features allow for individual lane forward error correction (FEC) pass-through. In addition, the DS560DF810 supports automatic lane rate switching for CDR lock up to five different combinations of baud rates and modulation types without host intervention.
The advanced equalization features of the DS560DF810 include a continuously adaptive continuous-time linear equalizer (CTLE), RX feed-forward equalizer (FFE), decision feedback equalizer (DFE), and a programmable, low-jitter 4-tap TX feed-forward equalizer (FFE) filter. These features enable reach extension for lossy interconnects such as direct-attach copper (DAC) cables and backplanes with multiple connectors and crosstalk.
