DATASHEET
2.4. Chip Specification
The tables below give the electrical specifications of the transceiver under the following conditions: Supply voltage VBAT1=
VBAT2=VDD=3.3 V, temperature = 25 °C, FXOSC = 32 MHz, F_RF = 915 MHz, Pout = +13dBm, 2-level FSK modulation
without pre-filtering, FDA = 5 kHz, Bit Rate = 4.8 kb/s and terminated in a matched 50 Ohm impedance, unless otherwise
specified. Matching as per Figure 39.
Note Unless otherwise specified, the performance in the 868 MHz band is identical or better.
