HP BANK64
The Zynq Ult MPSoC SBC supports 7 LVDS IOs/14 Single Ended (SE) IOs on Board to Board Connector2 from
MPSoC’s PL
High-Performance (HP) Bank64. Upon these 7 LVDS IOs/14 SE IOs, upto 1 HDGC Global Clock Inputs and
upto 5 PLSYSMON auxiliary analog inputs are available.
The IO voltage of PL Bank64 is connected from LDO1 output of the PMIC and supports variable IO voltage setting. IO
voltage is configurable from 1.2V to 1.8V through software. While using as LVDS IOs or Single Ended IOs, make sure to
set the PMIC LDO1 to output appropriate IO voltage for PL Bank64. By default, IO voltage of PL Bank64 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 Bank64 signals are routed as LVDS IOs to Board to Board Connector2. Even
though PL Bank64 signals are routed as LVDS IOs, these pins can be used as SE IOs if required. The Board to Board
Connector2 pins 15 and 16 are HDGC Global Clock Input capable pins of PL Bank64. Also Board to Board Connector2
pins 1, 2, 5, 6, 7, 8, 11, 12, 13, and 14 are PLSYSMON auxiliary analog Input capable pins of PL Bank64.
For more details on PL HP Bank64 pinouts on Board to Board Connector2, refer the below table.
