represents a pin-to-pin delay for the worst case I/O placement with a full diagonal path across the device and combinational logic
implemented in a single LUT and LAB that is adjacent to the output pin.
(2) The maximum frequency is limited by the I/O standard on the clock input pin. The 16-bit counter critical delay will run faster than this number.

MAX II and MAX IIG devices are available in three speed grades: –3, –4, and –5, with
–3 being the fastest. Similarly, MAX IIZ devices are available in three speed grades: –6,
–7, and –8, with –6 being the fastest. These speed grades represent the overall relative
performance, not any specific timing parameter. For propagation delay timing
numbers within each speed grade and density, refer to the
chapter in the
MAX II Device Handbook.
