from Power-up (cold start)
(48.008 – 48)/48
(14.31818 MHz x 57/17 = 48.008 MHz)
Measured from 0.4V to 2.4V
Measured from 2.4V to 0.4V
Measured on rising and falling edge at 1.5V
Assumes full supply voltage reached within 1 ms
from power-up. Short cycles exist prior to
frequency stabilization.
Average value during switching transition. Used
for determining series termination value.
