Can the main RF circuit be removed for projects that do not need the main RF?

Generally speaking , No primary RF is required （GSM/WCDMA/LTE）, It only needs WCN When the function , You can do the following . After the schematic design is completed, the review must be initiated , Again double check Next .

1,26M The master clock hangs on transceiver Platform on , Can't delete transceiver, because audio DSP need CP modem initialization , and CP modemC Initialization contains a pair of transceiver The initialization ; At this time, except transceiver External RF All devices can be deleted ;TR The power supply （ Including capacitance ）、GND、SPI、CLK Keep it ,LVDS and RF Delete all ports . Clock scheme uses TCXO+32K, There is no need to calibrate .

2,26M The master clock hangs on PMU Project on ,audio Module and CP modem No connection , Can be removed transceiver; The clock scheme defaults to TCXO（WCN chip ）+TSX（PMU chip , Do not calibrate ）+32K Crystal reservation ; It can also be used. TSX only（ use WIFI calibration ）.
