Pin Functions
FM-IF Block
Pin
Function
S-meter output for MRC
18 and SNC
S-meter output for muting
32 drive and HCC
30 S-meter output for SD
S-meter output shift control
28 pin
LA1867NM
Unit (resistance:Ω, capacitance:F)
Equivalent internal circuit
Note
Constant current drive type
The slope can be changed by changing the
value of the S-meter output resistance.
The field strength can be shifted in the
positive or negative direction with an
external resistor on pin 28 without changing
the S-meter slope.
20 Noise canceller input
21 FM detector output
30 FM SD Adj
Noise canceller input
The input impedance is 50 kΩ.
FM detector output
Low impedance in FM mode
Pin 30
The comparison voltage is determined by
the external resistor.
Pin 30 is the S-meter output, and SD turns
on when it exceeds the internal supply
voltage.
