nRF24LE1 Preliminary Product Specification
The nRF24LE1 contains two high frequency oscillators and two low frequency oscillators. The primary high
frequency clock source is a 16MHz crystal oscillator. There is also a fast starting 16MHz RC oscillator,
which is used primarily to provide the system with a high frequency clock while it is waiting for the crystal
oscillator to start up. The low frequency clock can be supplied by either a 32kHz crystal oscillator or a
32kHz RC oscillator. External 16MHz and 32kHz clocks may also be used instead of the on-chip oscilla-
tors. See section
