78 / 86 page 5–20 Chapter 5: DC and Switching Characteristics Timing Model and Specifications MAX II Device Handbook © Novermber 2008 Altera Corporation Table 5–26 shows the external I/O timing parameters for EPM2210 devices. t CNT Minimum global clock period for 16-bit counter — 3.3 — 4.0 — 5.0 — ns f CNT Maximum global clock frequency for 16-bit counter — — 304.0 (1) — 247.5 — 201.1 MHz Note to Table 5–25: (1) The maximum frequency is limited by the I/O standard on the clock input pin. The 16-bit counter critical delay performs faster than this global clock input pin maximum frequency. Table 5–25.
