10 The FPGA 2.5V I/O VOH level is insufficient to achieve EPCQ or EPCQ-A VIH threshold across entire voltage range.
11 The minimum VOH for 3V or 3.3V LVTTL is 2.4V in the Intel® FPGA device. This specification is based on the worst condition. Since the input current of EPCQ and EPCQ-A is small enough, the VOH of Intel® FPGA device does not violate the minimum VIH of EPCQ and EPCQ-A in the usual usage. Intel® recommends that you perform simulation using the IBIS model to ensure the required specifications are achieved.
12 0.2 V for EPCQ16A, EPCQ32A, EPCQ64A, and EPCQ128A. 0.4 V is for EPCQ4A
