6.6 System Oscillators Timing Requirements

over operating free-air temperature range(unless otherwise noted)

PARAMETER		TEST CONDITIONS	MIN	MAX	UNIT
SYSTEM OSCILLATORS
f_clock	Clock frequency, MOSC⁽¹⁾		19.998	20.002	MHz
t_c	Cycle time, MOSC⁽¹⁾		49.995	50.005	MHz
t_w(H)	Pulse duration⁽²⁾, MOSC, high	50% to 50% reference points (signal)	20		ns
t_w(L)	Pulse duration⁽²⁾, MOSC, low	50% to 50% reference points (signal)	20		ns
t_t	Transition time⁽²⁾, MOSC, tt = tf /tr	20% to 80% reference points (signal)		12	ns
t_jp	Period Jitter⁽²⁾, MOSC (This is the deviation in period from the ideal period due solely to high frequency jitter).			18	ps

(1) The frequency range for MOSC is 20 MHz with +/-100 PPM accuracy (it includes impact to accuracy due to aging, temperature and trim sensitivity). The MOSC input cannot support spread spectrum clock spreading.

(2) Applies only when driven via an external digital oscillator.
