Output Details

Output Compatability

HCMOS

Drive Capability

15pF max

Start Up Time: 10ms max

Output Control

Standby Operation:

Logic '1' (>70% Vs) to pad 2 enables oscillator output

Logic '0' (<30% Vs) to pad 2 disables oscillator output: when

disabled the oscillator output goes to the high impedance state

No connection pad 2 enables oscillator output

Output Levels

VoH: >90% of Vs

VoL: <10% of Vs

Noise Parameters

Period Jitter (pk-pk): 100ps max

Period Jitter (one sigma): 25ps max

Environmental Parameters

Storage Temperature Range: -55 to 125°C

Drop: 1.2m drop (3 times) onto a hard surface

Vibration: 1.5mm amplitude, 10-55-10Hz, full sine wave, 2mins

in 3 mutually perpendicular planes, duration 2hrs in each

plane
