LVCMOS33D
All I/O banks support emulated differential I/O using the LVCMOS33D I/O type. This option, along with the external
resistor network, provides the system designer the flexibility to place differential outputs on an I/O bank with 3.3V
VCCIO. The default drive current for LVCMOS33D output is 12mA with the option to change the device strength to
4mA, 8mA, 16mA or 20mA. Follow the LVCMOS33 specifications for the DC characteristics of the LVCMOS33D.
