Notes:

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.

For applications that use the major bands covered by Si4463/61/60, customers should use those parts instead of

Si4464.

Guaranteed by qualification. Qualification test conditions are listed in the "Qualification Test Conditions" section in "1.1.

Definition of Test Conditions" on page 14.

The maximum data rate is dependant on the XTAL frequency and is calculated as per the formula:

Maximum Symbol Rate = Fxtal/60, where Fxtal is the XTAL frequency (typically 30 MHz).

Default API setting for modulation deviation resolution is double the typical value specified.

Output power is dependent on matching components and board layout.
