NJM2590/97 DESCRIPTION 1. FSK comparator (FSK COMP) FSK comparator is a wave shaping circuit. When the demodulated FSK signal is weak or noisy, the computer may fail to read this signal. To prevent the read-error, the wave shaping circuit will ...

Page 11

Carrier sense The result of comparator is output to pin13 by comparing the output voltage of pin11 with external reference voltage of pin 12. Because pin13 is an open-collector terminal, an external resistor can be connected to another power ...
