Patent ID: 8325647

Claim:
A time-division multiplexer for multiplexing a first group of n (where n is an integer more than 1) input signals, and a second group of n input signals, thereby generating n multiplexed signals, comprising: n signal transition detection sections, each of which is configured to receive a corresponding one of the first group of n input signals, or a corresponding one of the second group of n input signals, and to detect a signal transition of at least one of the corresponding one of the first group of n input signals, or the corresponding one of the second group of n input signals; a time-division control section configured to output a control pulse according to a system clock when a signal transition is detected by at least one of the n signal transition detection sections; and n output switching sections, each of which is configured to receive a corresponding one of the first group of n input signals, or a corresponding one of the second group of n input signals, and to output either the corresponding one of the first group of n input signals or the corresponding one of the second group of n input signals as one of the n multiplexed signals according to the control pulse.
