The DS560DF410 is a four-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 DS560DF410 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 ideal 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 DS560DF410 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 DS560DF410 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.
The DS560DF410 is equipped with a bit mux and de-mux gearbox for simple NRZ-to-PAM4 or PAM4-to-NRZ conversion between host and module. The gearbox is capable of aggregating a pair of NRZ inputs up to 28.9 GBd into one 28.9 GBd PAM4 output as well as de-aggregating a single 28.9 GBd PAM4 input into a pair of 28.9 GBd NRZ outputs.
The DS560DF410 implements a full 2×2 crosspoint between each pair of adjacent channels after the CDR to enable fast and flexible lane switching for PCB routing flexibility, 2-to-1 multiplexing and 1-to-2 de-multiplexing for failover redundancy, and 1-to-2 fanout for diagnostic monitoring. In addition, integrated physical AC coupling capacitors (TX and RX) eliminate the need for external capacitors on the PCB. These features reduce PCB routing complexity and bill of material (BOM) cost.
Diagnostic capabilities include a non-destructive PAM4/NRZ vertical eye height monitor, a 2D PAM4/NRZ eye opening monitor (EOM), PRBS pattern generator with error injector module, PRBS error checker, and on-die temperature sensor. These features help to gauge the margin of the link and can be used to monitor the health of the system over time.
The DS560DF410 can be configured either through I2C or through an external EEPROM. Up to 16 devices can share a single EEPROM.
