Notes:
1. Holdover includes frequency stability (±0.28 ppm), supply voltage change(±5%) and aging for 24 hours.
2. TCXO: Initial calibration @ 25°C. Specification at time of shipment after 48 hours of operation.
3. Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C.
4. Inclusive of calibration @ 25°C, frequency vs. change in temperature, change in supply voltage (±5%), load change (±5%), reflow soldering process and 10 years aging
