12. Control Terminal for Quick Charge Circuit (CHARGE)
CHARGE (15 pin) is control terminal for quick charge circuit. REF (20 pin) control terminal for quick
charge a given period by time constant of internal resistance and outside capacitance. Enabling the
CHARGE pin requires an external capacitor. In normal operation, connect a capacitor having the same
capacitance as that of the capacitor connected to the REF pin (pin 20).
If the connected external capacitor (C11) is 0.1
μ
F, the quick charge time is 7 ms (typically).
13. Bit Rate Filter for FM
The current FM bit rate filter is used as a tertiary filter.
If the filter is to be used at a rate other than 1200 bps, please change the filter constant.
