I am studying hardware of different Qualcomm processors. WCN3620 is a chip used for wireless connectivity in Snapdragon 2100 and dragonboard. I could find only limited documentation on WCN3620. I want to look into the details of WLAN LO synthesize and distribution section present in WLAN section of the device. I want to know whether there is a Volage Controlled Oscillator and PLL present in this section. Can anyone please provide the detailed circuit of this section or let me know where to find this information.
