Note 1)
Supply Voltage Variation (@ ±5% change):
Frequency <20MHz: ±0.1ppm typ
Frequency 20MHz to <35MHz: ±0.3ppm typ
Frequency 35MHz to 52MHz: ±0.5ppm typ
Load Variation (@ ±5pF change):
Frequency <20MHz: ±0.2ppm typ
Frequency 20MHz to <35MHz: ±0.3ppm typ
Frequency 35MHz to 52MHz: ±0.5ppm typ
Note 1 Ageing:
Frequency ≤20MHz: ±1ppm max in 1st year
Frequency ≤20MHz: ±3ppm max for 10 years (including the 1st
year)
Frequency >20MHz: ±2ppm max in 1st year
Frequency >20MHz: ±5ppm max for 10 years (including the 1st
year)
Electrical Parameters
3.3V ±10%
Supply Voltage
Supply Current (typical):
HCMOS:
1+Frequency(MHz)*Supply(V)*{Load(pF)+15}*10–3mA
e.g. 20MHz, 3.3V, 15pF ≈ 3mA
Supply Voltage Tolerance: Parts will operate correctly with
±10% supply voltage variation but supply coefficient is
measured with ±5% variation
Frequency Adjustment - option B
No frequency adjustment
Initial calibration: ≤ ±1.0ppm
