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)
Use a simple LC filter (1.6nH and 1.8pF in parallel to ground) to pass ETSI conducted requirements below 1GHz
in restricted bands. For radiated measurements low antenna gain for these frequencies (depending on antenna
design) can achieve the same attenuation of these low frequency components (see EM reference design).

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
