nRF9E5 Single Chip Transceiver with Embedded Microcontroller and ADC
9.3
Standby mode is used to minimize average current consumption while not transmitting
or receiving and still maintaining short start up times to ShockBurst
ShockBurst
configuration word content is maintained during standby.
9.4
The power amplifier in nRF905 can be programmed to four different output power
settings by the configuration register. By reducing output power, the total TX current is
reduced.
9.5
The modulation of nRF905 is Gaussian Frequency Shift Keying (GFSK) with a data-rate
of 100kbps. Deviation is
effective transmission-link compared with ordinary FSK modulation.
The data is internally Manchester encoded (TX) and Manchester decoded (RX). That is,
the effective symbol-rate of the link is 50kbps. By using internally Manchester
encoding, no scrambling in the microcontroller is needed.
