Pin Functions
1
FM DET OUT
Audio FM detector output.
Deemphasis is switched internally in the IC. (5 k
and 7.5 k)
This switching is linked to the SIF input switch. An external
emitter-follower circuit must be provided if the deemphasis is
disabled.
2
SIF FILTER
Connection for a filter that holds the FM detector output DC
voltage at a fixed level. Normally, a 1-F electrolytic capacitor is
used. To improve the low band (around 50 Hz) frequency
characteristics, increase the value of this capacitor (C1).
5
6
VIF IN
VIF amplifier input.
The input circuit is constructed as a balanced input, and the
input has the following impedance characteristics:
R
≈ 1.5 k
C
≈ 3 pF
