HP BANK65 & 67
The Kintex Ult FPGA SOM supports 4 DIFF IOs/9 Single Ended (SE) IOs on Board-to-Board Connector1 from FPGA High-
Performance (HP) Bank65 and 1 DIFF IOs/5 Single Ended (SE) IOs from FPGA High-Performance (HP) Bank67 Upon these 5 DIFF
IOs/14 SE IOs, up to 4 HDGC Global Clock Inputs are available.
The IO voltage of Bank65 is connected from LDO2 and Bank67 is connected from LDO4 output of the PMIC and supports variable
IO voltage setting. IO voltage is configurable from 1.14V to 3.3V through software. While using as DIFF IOs or Single Ended IOs,
make sure to set the PMIC LDO2 & LDO4 to output appropriate IO voltage for Bank65 & 67. By default, IO voltage of Bank65 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, Bank65 & 67 signals are routed as DIFF IOs to Board-to-Board Connector1. Even though Bank65
& 67 signals are routed as DIFF IOs, these pins can be used as SE IOs if required. The Board-to-Board Connector1 pins 116, 118, 124,
126, 130, 132, 142 and 144 are HDGC Global Clock Input capable pins of Bank65.
For more details on HD Bank65 & 67 pinouts on Board-to-Board Connector1, refer the below table.
