Application Circuit
< Instructions of Application Circuits >
1 ) In case of using base band input, ICs were adjusted to perform good separation when input level ismatched
with 100 mV[rms] ( = 283 mV[p-p] ) on condition of mono 100% mod pre-emphasis OFF.
However, if good enough separation can't be taken in the cause of un-matching frequency characteristic and so in
input signal, it can adjust separation by connecting a volume between #22Pin and GND for adjusting high frequency separation.
If it not need adjusting separation, please open #22Pin.
If it need adjusting low frequency separation also, please adjust the input level volume for taking best separation on low frequency.
2 ) In case of using SIF input, please set up the SIF input level from tuners between 80 dBµV to 110 dBµV in standard
RF input conditions. Please select SIF - BPFs that group delay of 4.5 MHz 42 kHz is flat as possible.
3 ) In measuring characteristics of separation, please use the stereo modulator that perform good characteristic on dbx
encoder and corrected well.
In case of using SIF input, please correct FM modulation band to 25 kHz exactly at mono 100% mod pre-emphasis
OFF with the 0 carrier method.
And, please use LPFs that reduce 30 kHz signal over 20 dB setting between line-outs and AB level meter
