PAM-4 DATA TRANSMITTING DEVICE FOR MODULATING AMPLITUDE OF PAM-4 SIGNAL BY USING TOGGLE SERIALIZER AND OPERATING METHOD THEREOF

摘要

The present invention discloses a data transmitting apparatus for modulating the amplitude of a PAM-4 signal using a toggle serializer and an operation method thereof. According to an embodiment of the present invention, a data transmitting apparatus detects a logical level change of the first signal and the second signal in a pulse amplitude modulation (PAM) signal including a first signal and a second signal A toggle serializer for generating at least one toggle signal, and a driver for modulating the amplitude of the pulse amplitude modulation (PAM) signal by combining the first signal, the second signal, and the at least one toggle signal .
