HD BANK43
The Zynq Ult MPSoC SBC supports 11 LVDS IOs/22 Single Ended (SE) IOs on Board to Board Connector3 from
MPSoC
’s
PL High-Density (HD) Bank43. Upon these 11 LVDS IOs/22 SE IOs, upto 3 HDGC Global Clock Inputs and upto
11 PLSYSMON auxiliary analog inputs are available.
The IO voltage of Bank43 is connected from LDO6 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 LDO6 to output appropriate IO voltage for PL Bank43. By default, IO voltage of PL Bank43 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 Bank43 signals are routed as LVDS IOs to Board to Board Connector3. Even
though PL Bank43 signals are routed as LVDS IOs, these pins can be used as SE IOs if required. The Board to Board
Connector3 pins 41, 42, 43, 44, 53 and 54 are HDGC Global Clock Input capable pins of PL Bank43. Also Board to Board
Connector3 pins 31, 32, 33, 34, 35, 36, 39, 40, 41, 42, 43, 44, 47, 48, 49, 50, 51, 52, 53, 54, 58, and 60 are PLSYSMON
auxiliary analog Input capable pins of PL Bank43.
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.
