a. All specifications are single ended. Unused inputs are left open.
b. All specifications, except typical, are for industrial temperatures.
c. Typical operating conditions are 3.3V VBAT and 25°C ambient temperature. The final TX power depends on the insertion loss due to the
connector and the antenna. Typically, less than 2 dB. However, the actual value depends on the connector and antenna and must be
measured. The stated number is for chip output power.
d. The receiver sensitivity is measured at BER of 0.1% on the device interface.
e. Typical GFSK CI numbers at –7 MHz, –5 MHz, and –3 MHz are –45 dB, –42 dB, and –41 dB, respectively.
f.
Typical QPSK CI numbers at –7 MHz, –5 MHz, and –3 MHz are –46 dB, –43 dB, and –42 dB, respectively.
g. Typical 8PSK CI numbers at –7 MHz, –5 MHz, and –3 MHz are –50 dB, –45 dB, and –45 dB, respectively.
h. Meets this specification using front-end band pass filter.
i.
j.
Numbers are referred to the pin output with an external BPF filter.
f0 = -64 dBm Bluetooth-modulated signal, f1 = –39 dBm sine wave, f2 = –39 dBm Bluetooth-modulated signal, f0 = 2f1 – f2, and |f2 –
f1| = n*1 MHz, where n is 3, 4, or 5. For the typical case, n = 4.
k. Includes baseband radiated emissions.
