AMIS-52150
Low-Power Transceiver with Clock and Data Recovery
Data Sheet
Figure 10: Sniff Timing at RF Energy Detection
9.4 Quick Start
There are two oscillators in the AMIS-52150, a low power 10kHz RC oscillator and a crystal oscillator, respectively.
The RC oscillator is used to keep the AMIS-52150 running in the ultra-low power mode. This oscillator is used to generate the clock
signals for the Sniff Mode
timers as well as the wake-up timers. Figure 11 shows a block diagram of the clocks in the AMIS-52150.
The crystal oscillator provides the reference frequency which is used to generate the RF frequencies for transmission and receiving of
data. It is also the reference for all the timing functions in the AMIS-52150. The RC oscillator is in turn used to produce a “kicker” signal
when the Quick Start function of the crystal oscillator is needed.
