Measured on rising edge at 1.25V
Duration of clock cycle above 2.0V
Duration of clock cycle below 0.4V
Measured from 0.4V to 2.0V
Measured from 2.0V to 0.4V
Measured on rising and falling edge at
1.25V
Measured on rising edge at 1.25V. Max-
imum difference of cycle time between
two adjacent cycles.
Measured on rising edge at 1.25V
Assumes full supply voltage reached
within 1 ms from power-up. Short cycles
exist prior to frequency stabilization.
Average value during switching transi-
tion. Used for determining series termi-
nation value.
