Frequency Range
1.8 to 50MHz
Tri-state HCMOS
Drive Capability 15pF max
±25ppm, ±50ppm, ±100ppm
(Inclusive of supply voltage and output load variations over
the operating temperature range)
–10 to 70°C (CFPS-39)
–40 to 85°C (CFPS-39I)
–55 to 125°C
Logic ‘1’ (>70% Vs) to pad 1 enables oscillator output
Logic ‘0’ (<30% Vs) to pad 1 disables oscillator output;
when disabled the oscillator output goes to the high
impedance state
No connection to pad 1 enables oscillator output
10µA max
10ms max
Shock: MIL-STD-202F, Method 213B (1000G, 0.5ms, 1/2
sine wave)
Vibration: MIL-STD-202F, Method 204D test condition D20G,
10-2000Hz, 4hrs in each X, Y, Z axis (total 12 hrs)
