Note: Attention : at CLKI amplitude H/L, its spec changes with CLKI frequency.
The voltage level which Duty of CLKI becomes 50% (High time = Low time) is defined as Vcenter.
The measurement points of Trckt and Tfckt change with CLKI frequency.
2MHz ≤ CLKI frequency ≤ 20MHz : defined by the change time between Vcenter + 0.30[v] and Vcenter - 0.30[v].
20MHz < CLKI frequency ≤ 27MHz : defined by the change time between Vcenter + 0.55[v] and Vcenter - 0.55[v].
The timing observation level of Tfreq is to be Vcenter (Duty=50%).
