Transmit data rate | 0.45 | 153.6 | kBaud | The data rate is programmable. See Section 5.7 for details.
NRZ or Manchester encoding can be used. 153.6 kBaud equals 153.6 kbps using NRZ coding and 76.8 kbps using Manchester coding. See Section 5.4.2 for details. Minimum data rate for OOK is 2.4 kBaud |

To comply with EN 300 220 and FCC CFR47 part 15 an external (antenna) filter, as implemented in the application circuit in Section 5.11, must be used and tailored to each individual design to reduce out-of-band spurious emission levels. Spurious emissions can be measured as EIRP values according to EN 300 220. The antenna (SMAFF-433 and SMAFF-868 from R.W. Badland) plays a part in attenuating the spurious emissions. If the output power is increased using an external PA, a filter must be used to attenuate spurs below 862 MHz when operating in the 868 MHz frequency band in Europe. Application Note AN036 CC1020/1021 Reducing Spurious Emission (SWRA057) presents and discusses a solution that reduces the TX mode spurious emission close to 862 MHz by increasing the REF_DIV from 1 to 7. |
