SX8723
ZoomingADC™ for Pressure and Temperature Sensing
ADVANCED COMMUNICATIONS & SENSING
RC Oscillator
This block provides the master clock reference for the chip. It produces a clock at 4 MHz which is divided
internally in order to generate the clock sources needed by the other blocks.
The oscillator technique is a low power relaxation design and it is designed to vary as little as possible over
temperature and supply voltage.
This oscillator is trimmed at manufacture chip test.
The RC oscillator will start up after a chip reset to allow the trimming values to be read and calibration registers
and I2C address set to their programmed values. Once this has been done, the oscillator will be shut down and
the chip will enter a sleep state while waiting for an I2C communication.
