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).
