Note 1: All voltages are referenced to ground.
Note 2: This is the change in output frequency due to changes in voltage at T_A = +25°C.
Note 3: This is the change in output frequency due to changes in temperature from the +25°C frequency at V_CC = 3.3V.
Note 4: Guaranteed by design.
Note 5: This indicates the time elapsed between power-up and the output becoming active. An on-chip delay is intentionally intro-
duced to allow the oscillator to stabilize. t_STAB is equivalent to approximately 512 clock cycles and will depend on the pro-
grammed oscillator frequency.
Note 6: Output disabled in 2 cycles or less of the output frequency.
Note 7: Output voltage swings may be impaired at high frequencies combined with high-output loading.
Note 8: Typical frequency shift due to aging is within ±0.2%. Aging stressing includes level 1 moisture reflow preconditioning (24hr
+125°C bake, 168hr +85°C/85%RH moisture soak, and three solder reflow passes +240°C +0°C/-5°C peak) followed by
1000hr (max) V_CC biased +125°C OP/L, 1000hr unbiased +150°C bake, 1000 temperature cycles at -55°C to +125°C and
168hr +121°C/2 ATM steam/unbiased autoclave.
