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. Guaranteed by qualification. BER is specified for the 450–470 MHz band. Qualification test conditions are listed in the
"Qualification Test Conditions" section in "1.1. Definition of Test Conditions" on page 14.
4. For PER tests, 48 preamble symbols, 4 byte sync word, 10 byte payload and CRC-32 was used. PER and BER tested
in the 450–470 MHz band.
5. Guaranteed by bench characterization.
