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 E?
MIL-STD-883C, method 3015. Do not operate or store near strong electrostatic ?elds.
4. Speci?cation for packaged product only.
5. Sensitivity is de?ned as the average signal level, measured at the input, necessary to achieve 10 -2 BER (bit error rate). The input signal is de?ned
as a return-to-zero (RZ) waveform with 50% average duty cycle (Manchester encoded data) at a data rate of 600bps. The RF input is assumed to
be matched into 50Ω.
6. Sensitivity, a commonly speci?ed receiver parameter, provides an indication of the receiver ’s input referred noise, generally input thermal noise.
However, it is possibl?
noise is appreciab?
A better indicator of achievable receiver range performance is usually given by its selectivity, often stated as intermediate frequency (IF) or radio
frequency (RF) bandwidth, depending on receiver topology. Selectivity is a measure of the rejection by the receiver of ambient noise. More selective
receivers will almost inva? -
ally thermal will the receiver demonstrate sensitivity-limited performance.
7. Parameter scales linearly with reference oscillator frequency f T . For any reference oscillator frequency other than 6.7458MHz, compute the param-
eter value as the ratio:
× (parameter value at 6.7458MHz)

Example: For reference oscillator freqency f T = 6.00MHz:

9. Series resistance ?
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 50Ω and 100Ω respectively. Refer to “Application Hint 35” for crystal recommendations.
10. Parameter scales inversely with reference oscillator frequency f T . For any reference oscillator frequency other than 6.7458MHz, compute the
parameter value as the ratio:
