Output Compatibility
Drive Capability
10kΩ//10pF ±10%
Output: DC coupled
Note: a 1000pF DC-cut capacitor is to be connected in the
output line of the TCXO.
Output Level: 0.8V pk-pk min
Start Up Time: Vout
≥90%
of V pk-pk: 2ms max
Start Up Time (within ±0.5ppm): 2ms max
Output Control
Enable/Disable (pad 1):
Logic ‘1’ (80%Vs min) or no connection to pad 1 enables the
oscillator output.
Logic ‘0’ (20%Vs max) to pad 1 disables the oscillator output,
the output goes to a high impedance state.
Disable current in E/D mode: 3μA max
