1Edge rate in system is measured from 0.8V to 2.0V.
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

1Edge 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.
