Circuit diagram (sheet 10)
The oscillator output signal TCXO is connected to the power management IC (PMIC, N1300, Pin
58).
The oscillator output signals RFR6250_TCXO and RTR6250_TCXO are connected to the RF chips
RFR6250 (N600, Pin 33) resp. RTR6250 (D500, Pin 6).
To compensate frequency drifts the oscillator frequency is controlled by the TRX_LO_ADJ signal,
generated through the MSM6250 (D800, SW_TP902).
