1Edge rate in system is measured from 0.8V to 2.0V at default slew rate control setting.
2 Duty cycle, Peroid and Jitter are measured with respect to 1.5V
3 The average period over any 1us period of time
NOTES: (unless otherwise noted, guaranteed by design and characterization, not 100% tested in production).
4 Using frequency counter with the measurment interval equal or greater that 0.15s, target frequency is 14.318180 MHz

1 Edge rate in system is measured from 0.8V to 2.0V at default slew rate control setting.
2 All Long Term Accuracy and Clock Period specifications are guaranteed assuming that REF out is at 14.31818MHz
3 At nominal temperature and voltage.
4 Long term and peak to peak jitter do not apply to the 27MHz spreading output. The spread modulation directly impacts these values.
NOTES: (unless otherwise noted, guaranteed by design and characterization, not 100% tested in production).
