It is recommended the next layer under the keep out area is to be ground plane. Notes: 1. Medium term stability (Specified and measured according to the latest release of " Specification for Cospas-Sarat-406 MHz distress Beacon" C/S T.001 . Averaged over 18 measurements in 15 minute period and following 15 minute warm up.) 2. Frequency referenced to Fo. 3. Frequency stability vs. change in temperature. [±(Fmax - Fmin)/(2*Fo)]. 4. Referenced to 15 pF , ±5%. 5. dT/dt <±5°C/hour 6 Attention: To achieve optimal frequency stability, and in some cases to meet the specification stated on this data sheet, it is required that the circuit connected to this TCXO output must have the equivalent input capacitance that is specified by the nominal load capacitance. Deviations from the nominal load capacitance will have a graduated effect on the stability of approximately 20 ppb per pF load difference. 7. Oscillator and compensation circuit are still active when output is disabled during tri-state mode. Output is enabled with no connection on pad 8. Supply current is ~ 1mA when output is disabled.
