1. Boost_SNS pin needs routing to VREG_BOOST
bypass cap (C1022/C1023) . Directly on bypass cap.

2. Boost_sns trace should be well isolated
from noisy traces especially from VSW_BOOST

1) Please connect GND_CP (pin 146) to C1004 GND.
Then connect to main PCB GND from C1004

2) Please connect GND_SPKR_PA (pin 120) to C1024 GND.
Then connect to Main PCB GND from C1024.

3) Please connect GND_BOOST (pins 151/152) to
C1022/C1023 GND.
Then connect to Main PCB GND from C1022/C1023.

Note: If best EMI practices are followed for MIPI CSI/DSI signals, there is no need
for common mode choke filters. You may choose to have placeholders for
common mode depending upon your design constraints.
Extreme care must be taken that no stubs are created by doing so.

Note: If best EMI practices are followed for MIPI CSI/DSI signals, there is no need
for common mode choke filters. You may choose to have placeholders for
common mode depending upon your design constraints.
Extreme care must be taken that no stubs are created by doing so.
