Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive, use appropriate ESD precautions. Meets class 1 ESD test requirements, (human body model HBM), in accordance with
MIL-STD-883C, method 3015. Do not operate or store near strong electrostatic fields.
4. Sensitivity is defined as the average signal level measured at the input necessary to achieve 10-2 BER (bit error rate). The RF input is assumed to be
matched to 50 ? .
5. Spurious reverse isolation represents the spurious components which appear on the RF input pin (ANT) measured into 50 ? with an input RF
matching network.
6. Parameter scales linearly with reference oscillator frequency f T . For any reference oscillator frequency other than 4.8970MHz, compute new
parameter value as the ratio:.

7. Parameter scales inversely with reference oscillator frequency f T . For any reference oscillator frequency other than 4.8970MHz, compute new
parameter value as the ratio:

8. Series resistance of the resonator (ceramic resonator or crystal) should be minimized to the extent possible. In cases where the resonator series
resistance is too great, the oscillator may oscillate at a diminished peak-to-peak level, or may fail to oscillate entirely. Micrel recommends that series
resistances for ceramic resonators and crystals not exceed 50Ohms and 100 ? respectively. Refer to Application Hint 35 for crystal
recommendations.
