FREQUENCY_SHIFT_KEYER

Apply a signal to each differential amplifier input pair.When the gate voltage is changed from oneextreme to the other, the output can be switched alternately between the two input signals.When the gatelevel is high (1.5V), a signal applied between pms 5 and 6(channel A)will be passed and a signal appliedbetween pins 3 and 4(channel B)will be suppressed.In this manner,a binary-to-frequency conversion is obtained that is directly related to the binary sequence,which is driving the gate mput (pin 2).
