PCB Mounting Conditions to cover the FM Receiving Area of 76M to 108MHz
LV24230LP-A's PCB mounting conditions
LV24230LP-A has an inductor for local oscillator on the package bottom side.
In order to cover the receiving frequency range of 76MHz to 108MHz, provide the GND layer to the first layer of
Side A of PCB that is directly below the package bottom side, as shown in the figure.

With this SPL, the receiving frequency is measured under the following conditions :
The X-value can be set freely between Min = 2.4mm and Max = 3.0mm with reference to IC.
(The X-value for Sanyo Demo Board is 2.8mm.)
The Y-value can be set freely between Min = 2.0mm and Max = 3.0mm with reference to IC.
(The Y-value for Sanyo Demo Board is 2.6mm.)
Avoid providing another wiring within 0.4mm of bottom layer of PCB_GND as much as possible.
