NOTES

1 Operating temperature range is as follows: –40 C to +85 C.

2 Datarates should be limited to adhere to edge of band requirements in accordance with ETSI 300-220

3 Frequency Deviation = (PFD Frequency

Mod Deviation )/2

12.

GFSK Frequency Deviation = (PFD Frequency

m)/212 where m = Mod Control.

4 The output power is limited by the spurious requirements of ETSI at +55 C. 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 V

DD = 3 V, PFD = 4 MHz, PA = 10 dBm

6 V

DD = 3 V, Loop Filter BW = 100 kHz

7 V

DD = 3 V, PFD = 4.42368 MHz, PA = 3 dBm

8 V

DD = 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.

10 Not production tested. Based on characterization.

Specifications subject to change without notice.
