5 Description (continued)

The DS560DF810 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 DS560DF810 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 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 DS560DF810 can be configured either through I2C or through an external EEPROM. Up to 16 devices can

share a single EEPROM.
