Observe precautions for handling! 1. 2. 3. 4. 5. 6. 7. 8. 9. The frequency fC is the frequency of minimum IL with the resonator in the specified test fixture in a 50 Ω test system with VSWR ≤ 1.2:1. Typically, f OSCILLATOR or fTRANSMITTER is less than the resonator f C. Unless noted otherwise, case temperature T C = +25°C±2°C. Frequency aging is the change in f C with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures above +65°C. Typically, aging is greatest the first year after manufacture, decreasing in subsequent years. Turnover temperature, T0, is the temperature of maximum (or turnover) frequency, f 0. The nominal frequency at 2 any case temperature, TC, may be calculated from: f = f 0 [1 - FTC (T 0 - TC) ]. Typically, oscillator T0 is 20° less than the specified resonator T0. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance C 0 is the measured static (non-motional) capacitance between either Pin 1 and ground or Pin 4 and ground. The measurement includes case parasitic capacitance. Derived mathematically from one or more of the following directly measured parameters: f C, IL, 3 dB bandwidth, fC versus TC, and C0. The specifications of this device are based on the test circuit shown above and subject to change or obsolescence without notice. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufacturer. Our liability is only assumed for the Surface Acoustic Wave (SAW) component(s) per se, not for applications, processes and circuits implemented within components or assemblies.
