LV24100LP
The PCB mounting conditions which cover FM receiving frequency range 76MHz to 108MHz
This IC Package is printed inductor backside of the package for local oscillation. It is necessary to place GND pattern
right under the IC package for covering received frequency range 76MHz to 108MHz.
This IC is measured under this condition for received frequency range. Then, the GND pattern must be placed at the
center of the IC.

PCB pattern light under of LV24100LP
At the GND pattern light under of LV24100LP, X=3.4mm is recommended.
The limit of X is min=2.2mm and max=3.6mm same as GND shield size of LV24100LP.
Please do not arrange other wirings as much as possible within 0.4mm under the GND pattern.
