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 fields.

4. Specification for packaged product only.

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.

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

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.
