FUNCTION
INTERFACE CIRCUIT
16
QIF Output
QIF detection output terminal. Connect
this terminal to SIF input via BPF.
For BPF matching, see function of pin
17.
17
SIF Input
RF AGC SW
Connect to pin 16, via BPF.
This terminal also functions as output
polarity switching circuit of RF AGC
output.
Internal impedance is designed to be 2
k. Externally connecting 2 k
between this terminal and GND
outputs reverse AGC and changes
input impedance to 1 k.
Externally connecting a 2 k-resistor
between this terminal and VCC outputs
forward AGC and changes input
impedance to 1 k.
