WIRELESS & SENSING PRELIMINARY DATASHEET
FRC RC Oscillator frequency After calibration - 62.5 - kHz
BRF Bit rate, FSK Programmable values (1) 1.2 - 300 kbps
BRO Bit rate, OOK Programmable 1.2 - 32.768 kbps
BRA Bit Rate Accuracy ABS(wanted BR - available BR) - - 250 ppm
FDA Frequency deviation, FSK (1) Programmable
FDA + BRF/2 =< 250 kHz
0.6 - 200 kHz
Note For Maximum Bit rate the maximum modulation index is 0.5.
2.4.3. FSK/OOK Mode Receiver
All receiver tests are performed with RxBw = 10 kHz (Single Side Bandwidth) as programmed in RegRxBw, receiving a
PN15 sequence. Sensitivities are reported for a 0.1% BER (with Bit Synchronizer enabled), unless otherwise specified.
Blocking tests are performed with an unmodulated interferer. The wanted signal power for the Blocking Immunity, ACR,
IIP2, IIP3 and AMR tests is set 3 dB above the receiver sensitivity level.
