I/O Format

FM local

oscillation

input

This pin inputs local oscillation output (VCO output) of FM

band. It becomes active when FM band is received; oth-

erwise, it is internally pulled down.

Input frequency ranges from 15 to 150 MHz (0.3 Vp-p). Because

on-chip AC amplifier is provided, cut out DC component

with a capacitor.

Input

Ground pins.

Ground

GND0 is ground of PLL, and GND1 and GND2 are grounds

of digital circuits.

No connection Connect nothing to this pin.

Error out

These are output pins of charge pump of PLL (Phase

Locked Loop). If divided local oscillation frequency (VCO

output) is higher than reference frequency, these pins

output high level; if local oscillation frequency is lower

than reference frequency, these pins output low level.

They are floated if two frequencies match.

These outputs are input to external LPF (lowpass filter) and

are applied to varactor diode via LPF.

Same waveform is output to EO0 and EO1. You can use

either pin.
