6.1. System Clock Output

A clock output is available on CLK_OUT (pin 10) of the Si4356, which can be used to drive an external MCU and

avoid the need for additional oscillators in the application. The clock signal is valid when MSTAT is low. The clock

frequency is set to 10 MHz for 315 MHz RX frequency selection and 15 MHz for all other frequencies. If this clock

signal is not needed, then it can be turned off by connecting CLK_OUT (pin 10) to MSTAT/OUT0 (pin 12). The

clock signal is turned off during Standby and Device Reset modes.
