Description
56-pin SSOP (300 mils)
Package Type
Determined by PLL divider ratio (see m/n below)
(24.004 – 24)/24
(14.31818 MHz x 57/34 = 24.004 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 fre-
quency stabilization.
Average value during switching transition. Used
for determining series termination value.
