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)
Differential impedance as seen from the RF port (RF_P and RF_N)
Optimum load impedance 70 +j30 Ω
toward the antenna
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.

The crystal oscillator must be in power down for a guard
time before it is used again. This requirement is valid for
Power-down guard time 3 ms
all modes of operation. The need for power-down guard
time can vary with crystal type and load.
