Introduction to connectivity module troubleshooting
The WCN3660 module supports WLAN and BT.
REFCLK_I single ended 48 MHz analog clock from an external crystal (Y3300) is provided to WCN3660.
The clock request for the reference clock in the WCN3660 module is shared between WLAN and BT blocks.
When either system requires a clock, this signal will be active. The CLK_REQ is connected to LDO of 48
MHz crystal. The SLEEPCLK input of 32.768 KHz clock from EM ASIC (PMIC 8038) is used for power
management. The internal SMPS supplies the whole WCN3660 solution from the phone battery supply,
VBAT, apart from VIO which is needed for interface signal reference levels.
Baseband part of the connectivity functions is integrated into MSM8930/8230.
The following figure shows a top level block diagram of the WCN3660 module.
