HD BANK45
The Zynq Ult MPSoC SOM supports 11 LVDS IOs/22 Single Ended (SE) IOs on Board to Board Connector1
from MPSoC
’s
PL High-Density (HD) Bank45. Upon these 11 LVDS IOs/22 SE IOs, upto 3 HDGC Global Clock Inputs and
upto 8 PLSYSMON auxiliary analog inputs are available.
The IO voltage of PL Bank45 (& Bank46) is connected from LDO3 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 LVDS IOs or Single Ended IOs,
make sure to set the PMIC LDO3 to output appropriate IO voltage for PL Bank45. By default, IO voltage of PL Bank45
is set as 1.8V. For more details about supported IO standard, refer the Zynq Ult MPSoC datasheet.
In the Zynq Ult MPSoC SOM, PL Bank45 signals are routed as LVDS IOs to Board to Board Connector1. Even
though PL Bank45 signals are routed as LVDS IOs, these pins can be used as SE IOs if required. The Board to Board
Connector1 pins 22, 24, 56, 58, 82 & 84 are HDGC Global Clock Input capable pins of PL Bank45. Also Board to Board
Connector1 pins 12, 14, 18, 16, 27, 28, 29, 30, 31, 32, 33, 34, 38, 40, 42 & 44 are PLSYSMON auxiliary analog Input
capable pins of PL Bank45.
Note: In ZU7CG/7EG/7EV MPSoC devices, the PL Bank45 & PL Bank46 is called as PL Bank47 and PL Bank48
respectively. Only the Bank Numbering is different and all other functionalities remain same.
For more details on PL HD Bank45 pinouts on Board to Board Connector1, refer the below table.
