No.2208–6/7
The composite current after the level detection flows out from pin 14, and after its being converted to a voltage by
an externally connected circuit, will detremine V1 of the comparator.
The squelch circuit may be provided with hysteresis by providing a resistor feedback from pin 15 to pin 14.
(6) Data Shaper
The data shaper is a high-impedance input differential amplifier that provides an open-collector output. It serves to
facilitate the design for matching with a following stage (such as a CPU).
