Frequency Stability
±20ppm all causes over 15 years inclusive of frequency tolerance,
supply voltage variation, load variation and ageing.
Output Details
Logic ‘1’ to pad 1 enables oscillator output, 2.5V min.
Logic ‘0’ to pad 1 disables oscillator output; when disabled the
oscillator output goes to the high impedance state, 0.5V max.
No connection to pad 1 enables oscillator output.
