MachXO2: I don't see Differential 3.3v CMOS inputs (LVCMOS33D) input characteristics in the MachXO2 Data Sheet.  What are its specifications?

The LVCMOS33D buffer characteristics are similar to those of the LVDS33 differential input buffer, with these key differences:



  • Vinp/Vinm = 0v min, 3.4v max, 3.3v typ

  • Vcm = 2.6v max, 1.65v typ

  • Fmax = 136MHz
Note: The 100ohm internal termination resistor is not available for this input configuration.  It is available only for the LVDS input type.
