FPGA Interfaces
The interfaces which are supported in Board-to-Board Connector2 from Kintex Ult FPGA is explained in the following
section.

HP BANK66,65
The Kintex Ult FPGA SOM supports 24 LVDS IOs/48 Single Ended (SE) IOs on Board-to-Board Connector2 from FPGA
’s
High
Performance (HP) Bank66. Upon these 24 LVDS IOs/48 SE IOs, up to 4 GC Global Clock Inputs and up to 16 SYSMON auxiliary analog
inputs are available. From HP Bank65 2 Single Ended (SE) IOs also is available. The IO voltage of Bank66 is connected from LDO3
output of the PMIC and supports variable IO voltage setting. IO voltage is configurable from 0.95V to 1.8V through software. While
using as LVDS IOs or Single Ended IOs, make sure to set the PMIC LDO3 to output appropriate IO voltage for Bank66. By default, IO
voltage of Bank67 is set as 1V 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, Bank66 signals are routed as LVDS IOs to Board-to-Board Connector2. Even though Bank66
signals are routed as LVDS IOs, these pins can be used as SE IOs if required. The Board-to-Board Connector2 pins 169, 170, 171,
172, 176, 178, and 177 are GC Global Clock Input capable pins of Bank66. Also, Board to Board Connector2 pins 122, 124, 126, 128,
132, 134, 135, 136, 137, 138, 144, 146, 147, 148, 149, 150, 151, 153, 155, 156, 157, 158, 159, 161, 163, 164, 166, 181, 182, 183 and
184 are SYSMON auxiliary analog Input capable pins of Bank66.
