NOTES
1Operating temperature range is as follows: –40ЊC to +85ЊC.
2Datarates should be limited to adhere to edge of band requirements in accordance with ETSI 300-220
3Frequency Deviation = (PFD Frequency ؋ Mod Deviation )/212.
GFSK Frequency Deviation = (PFD Frequency ؋ 2m)/212 where m = Mod Control.
4 The output power is limited by the spurious requirements of ETSI at +55 ЊC. The addition of an output filter (see Applications section) will allow increased output
levels to >10 dBm at both 433 MHz and 868 MHz
5 VDD = 3 V, PFD = 4 MHz, PA = 10 dBm
6 VDD = 3 V, Loop Filter BW = 100 kHz
7 VDD = 3 V, PFD = 4.42368 MHz, PA = 3 dBm
8 VDD = 3 V, Loop Filter BW = 100 kHz
9 These spurious levels are based on a maximum output power of +3 dBm for 868 MHz and +10 dBm for 433 MHz. It assumes a PFD frequency of <5 MHz.
Recommended PFD frequencies are 4.42368 MHz (22.1184/5) for 868 MHz, and 4 MHz for 433 MHz operation. Compliance for higher output powers will require
an external filter. See Applications section.
