Application Note
1. PW SW
It is necessary to connect an external pull-down resistor with the terminal PW SW (pin(7)), in case that this IC
is turned on due to external noise etc.
2. MODE SW
It is necessary to connect an external pull-down resistor with the terminal MODE SW (pin(6)), in case that this
IC doesn't operate normally due to external noise etc.
3. RF GND
This IC has two GND terminals (pin(3): RF GND, pin(16): GND). External parts shown in below should be
connected with RF GND (pin(3)), and other parts should be connected with GND (pin(16)).
･ By-pass capacitor at pin(14) (FM RF) and pin(15) (TV RF)
･ By-pass capacitor at pin(4) (FM BY) and pin(2) (TV BY)
The pattern diagram of capacitor connected with pin(2) and pin(4) should be shortly, because RF circuit and MIX
circuit operate on the voltage of pin(2) or pin(4).
