Electrical parameters are guaranteed by design with these operating conditions, unless otherwise noted.
External input reference clock must have a duty cycle between 40% and 60%, measured at V
/2.
Please refer to application note
“
Crystal Oscillator Topics
”
for information on AC-coupling the external input reference clock.
The oscillator circuit is optimized for a crystal reference and for external reference clocks up to 20 MHz. For external reference clocks above 20 MHz, it is
recommended that a 150
pull-up resistor to V
DD
be connected to the Xout pin.
Xtal inputs have CMOS thresholds.
