TP0332/2
The synthesizer, IC401, contains two synthesizer circuits. The second circuit is used for the
generation of the receiver second local oscillator (output control signal AUX_CP). This removes the need
for the alignment of this oscillator because the frequency is locked to the TCXO and allows its frequency to
be varied to avoid potential interference. The second local oscillator is switched off during transmissions.
The second local oscillator frequency is applied to the synthesizer as AUX_LO2.
