Table 3: Operating Range
(*) For narrow-band configurations (base-band filter bandwidths of 10, 20 and 40 kHz), the minimum operating
supply voltage is 2.4 V. For 200 kHz base-band filter bandwidth setting the minimum operating supply voltage is 2.7
V.
3.2.2 Electrical Specifications
The table below gives the electrical specifications of the transceiver under the following conditions:
Supply Voltage = 3.3 V, temperature = 25 °C, 2-level FSK without pre-filtering, fC = 434, 869 and 915 MHz,
∆f = 5 kHz, Bit rate = 4.8 kbits/s, BWSSB = 10 kHz, BER = 1 % (measured at the output of the bit synchronizer), LNA
input and PA output matched to 50 Ω, environment as defined in section 6, unless otherwise specified.
