System Module
RF clock is used by RAPIDOYawe, which provides 19.2MHz SysClk to the application processor. Both
RAPIDOYawe and Nomadik have internal PLL's that create clock signals for other peripheral devices/interfaces
like SD card, SIM, CCP, I2C and memories.
BT and WLAN have their own 38.4MHz crystal oscillator that generates clock signal when clock request from
either WLAN or BT is high.
32k Sleep Clock is always powered on after startup. Sleep clock is used by RAPIDOYawe and Nomadik
application processor for low power operation. Sleep clock is also used by GPS, FM Radio, Bluetooth and WLAN.
For RAPIDOYawe and GPS the sleep clock is not buffered, for other modules the sleep clock is buffered (VIO_APE
is the buffer power supply).
SMPS Clk is a 2.4MHz clock line from RAPIDOYawe to EM ASIC Betty (N2300) and discrete SMPS N2390. In deep
sleep, when VCTCXO is off, this signal is set to '0' state.
12 MHz Camera Clock is generated by Nomadik.
