Application notes

1. Short circuiting: all pins are short-circuit proof except pin 1 (FM-RFI) with respect to the supply voltage pin.

2. Tuning indicator (at pin 15, IND): connect either a tuning indicator (e.g. a LED) between this pin and the supply

voltage (pin 16) or connect the pin IND to ground.

3. For an example of PC-board layout: see Figs 6 and 7.
