Notes:
1. All specification guaranteed by production test unless otherwise noted. Production test conditions and max limits are
listed in the “Production Test Conditions” section in "1.1. Definition of Test Conditions" on page 14.
2. For applications that use the major bands covered by Si4463/61/60, customers should use those parts instead of
Si4464.
3. Default API setting for modulation deviation resolution is double the typical value specified.
4. Guaranteed by qualification. Qualification test conditions are listed in the "Qualification Test Conditions" section in "1.1.
Definition of Test Conditions" on page 14.
