12311-MRB
The 12311-MRB utilizes a flexible RF path topology that make it suitable for working in different
frequency bands by replacing a minimum number of components while providing good RF performance.
Following Tables shows the different BOM according to different Frequency Bands of operation.

32 MHz Reference Oscillator -
mounted crystal must meet the MC12311 specifications.
— Capacitors C22 and C25 provide the bulk of the crystal load capacitance.
— Signal DIO5/CLKOUT can be used to supply an external clock to MCU die and to measure a
— The 12311-MRB has provision for injecting an external 32 MHz clock source as an alternative
Optional 32.768 kHz Crystal Oscillator - Provision is also made for a secondary 32.768 kHz crystal

the 32MHz oscillator frequency.
to use of the onboard crystal:
– The crystal Y1 should be removed
– C23 must be mounted
– The external 32 MHz source is connected to 2-pin header J4.
