HD BANK44
The Zynq Ult MPSoC SBC supports 12 LVDS IOs/24 Single Ended (SE) IOs on Board to Board Connector3 from
MPSoC
’s
PL High-Density (HD) Bank44. Upon these 12 LVDS IOs/24 SE IOs, upto 4 HDGC Global Clock Inputs and upto
8 PLSYSMON auxiliary analog inputs are available.
The IO voltage of Bank44 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 Bank44. By default, IO voltage of PL Bank44 is set as 1.2V
and after U-boot bootup configured to 1.8V. For more details about supported IO standard, refer the Zynq Ult
MPSoC datasheet.
In the Zynq Ult MPSoC SBC, PL Bank44 signals are routed as LVDS IOs to Board to Board Connector3. Even
though PL Bank44 signals are routed as LVDS IOs, these pins can be used as SE IOs if required. The Board to Board
Connector3 pins 5, 6, 7, 8, 11, 12, 17, and 18 are HDGC Global Clock Input capable pins of PL Bank44. Also Board to
Board Connector3 pins 1, 2, 3, 4, 13, 14, 15, 16, 21, 22, 23, 24, 25, 26, 29 and 30 are PLSYSMON auxiliary analog Input
capable pins of PL Bank44.
Note: In ZCU2 & ZCU3 MPSoC devices, the PL Bank 43, 44, 45 & 46 is called as 44, 24, 25 & 26 respectively. Only the
Bank Numbering is different and all other functionalities remain same.
For more details on PL HD Bank44 pinouts on Board to Board Connector3, refer the below table.
