UTC
and is larger values are used, POP noise occurs strongly.
This is the low pass filter fr the PLL, which is determined the capture range and THD at low frequency.
Pin6.
These components provide Right and Left channel output load circuits. The recommended circuits as follows:
The recommended value is 10µF. If smaller vlaues than 10ΩF are used, low frequency separation will worsens,
The VCO free running frequency is adjusted by connecting a frequency counter to monitor the 38kHz output of
