CALCULATING MAXIMUM FREQUENCY
Based on the rise and fall time data given in Table 1 through 5, the maximum frequency the oscillator can operate with
a guaranteed full swing of the output voltage over temperature is calculated as follows:
1
Example:
Calculate F
max
of a 1MHz ~ 110MHz device with the following condition:
º V
dd
= 1.8V (Table 1)
º Capacitive Load = 30pF
º Desired T
r/f
Time: = 3ns (rise/fall time option code “E”)
The F
max
is 66.66666MHz.
