To generate an EEPROM configuration, first configure the DS560MB410 redriver using the
High Level Page
and
Low Level Page
. Then press
Update Slot from Device
. This will update the selected EEPROM slot with the
device configuration. Multiple redrivers can have independent configurations in a single EEPROM hex file. Each
independent configuration is represented by the
Slot #
. After updating the slot from the device, the EEPROM hex
file can be saved by pressing the
Write to EEPROM Hex
button.
A hex file can be loaded and modified using the
EEPROM Page
as well. This can be done by loading the hex file
using the
Load from Hex File
button. Then, press
Update Device from Slot
to update the redriver settings from
the selected EEPROM hex file. After doing this, modifications can be made using the
High Level Page
and
Low
Level Page
. After making modifications, press
Update Slot from Device
to update the selected EEPROM slot
with the modified device configuration. The EEPROM hex file can then be saved using the
Write to EEPROM
Hex
button.

5.6 Eye Height Page
The DS560MB410 eye height monitor is an on-chip tool to help determine the ideal CTLE boost index range
for NRZ and PAM4 signals. This eye height monitor provides information about the eye height across a range
of EQ Boost Codes. For each EQ Boost Code, an internal DAC is swept through 64 steps. At each step, the
number of times the signal crosses the DAC voltage in a given time interval is recorded. This is recorded in
channel registers 0x22-0x25. The eye openings, shown in white, the on
Eye Height Page
correspond to DAC
voltages where the number of crossings did not change much between consecutive DAC values. From this data,
an optimum EQ Boost Code is recommended.
