CLOCK
OSCILLATORS
2.5V surface mount oscillator in a ceramic package, with a
hermetically sealed metal lid
5 x 3.2mm
1.8 to 125MHz
Tri-state CMOS
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-37)
–40 to 85°C (CFPS-37I)
–55 to 125°C
Logic ‘1’ (>70% Vs) to pad 1 enables oscillator output
Logic ‘0’ (<30% Vs) to pad 1 disables oscillator output
and oscillator output goes to the high impedance state
No connection to pad 1 enables oscillator output
10µA max
Shock: MIL-STD-202F, Method 213B (1000G, 0.5ms)
Vibration: MIL-STD-202F, Method 204D, Test Condition
D20G (10-2000Hz) 4 hrs in X, Y & Z axes (total 12 hrs)
