HD BANK92
The Kintex Ult FPGA SOM supports 11 DIFF IOs/22 Single Ended (SE) IOs on Board-to-Board Connector1 from FPGA High-
Density (HD) Bank92. Upon these 11 DIFF IOs/22 SE IOs, up to 3 HDGC Global Clock Inputs and up to 22 PLSYSMON auxiliary analog
inputs are available.
The IO voltage of Bank92 is connected from LDO1 output of the PMIC and supports variable IO voltage setting. IO voltage is
configurable from 1.2V to 3.3V through software. While using as DIFF IOs or Single Ended IOs, make sure to set the PMIC LDO1 to
output appropriate IO voltage for Bank92. By default, IO voltage of Bank92 is set as 1.2V and after U-boot bootup configurable to
1.8V. For more details about supported IO standard, refer the Kintex Ult FPGA datasheet.
In the Kintex Ult FPGA SOM, Bank92 signals are routed as LVDS IOs to Board-to-Board Connector1. Even though Bank92
signals are routed as DIFF IOs, these pins can be used as SE IOs if required. The Board-to-Board Connector1 pins 22, 24,70, 72, 87,
88, 89, ,90, 91, 93 are HDGC Global Clock Input capable pins of Bank92. Also, Board to Board Connector1 pins 12, 14, 16, 22, 24,
27, 29, 31, 33, 40, 44, 46, 48, 50, 70, 72, 87, 88, 89, 90, 91, 93, and are PLSYSMON auxiliary analog Input capable pins of Bank92.
For more details on HD Bank92 pinouts on Board-to-Board Connector1, refer the below table.
