downs (PD) can be enabled.

Upon power-on, the LM8335 default configuration is

for all GPO to be set based on the state of the CFG

pin.

After startup, any changes to the default configuration

must be sent from the host via the MIPI RFFE host

interface..

The LM8335 is available in a 16-bump lead-free

DSBGA package of size 1.965 mm x 1.965 mm x 0.6

mm (0.5 mm pitch).
