Notes:
3.
Electrical parameters are guaranteed with these operating conditions. Values for 3.3V operation are shown in parentheses.
4.
External input reference clock must have a duty cycle between 40% and 60%, measured at V
/2.
5.
Please refer to application note
“
Crystal Oscillator Topics
”
for information on AC-coupling the external input reference clock.
6.
Xtal inputs have CMOS thresholds.
7.
