measurement
Suitable for systems targeting compliance with worldwide radio-frequency regulations ETSI EN 300 328 and
EN 300 440 Class 2 (Europe), FCC CFR47 Part 15 (US), and ARIB STD-T66 (Japan)

Ω
Designs with antenna connectors that require conducted ETSI compliance at 64 MHz should insert an LC
resonator in front of the antenna connector. Use a 1.6-nH inductor in parallel with a 1.8-pF capacitor. Connect
both from the signal trace to a good RF ground.

Start-up time
Power-down guard time
The crystal oscillator must be in power down for a guard
time before it is used again. This requirement is valid for
all modes of operation. The need for power-down guard
time can vary with crystal type and load.
