Example of Synchronous Reset’s utility in case of de-synchronization of the DMUX output port
selection. The de-synchronization event happens after the selection of Port D.
DMUXDelAdjCtrl value is nominal. TSSR < 0 because of Clkln’s internal propagation delay
TCPD. After selection of Port C, instead of selecting Port D, the de-synchronization makes the
port selection to restart on Port A. Since Port H was not selected, the data is not output to the
ports but the last data (d1 to d8) is latched until the next selection of Port H. d9 to d16 are lost.
The synchronous Reset ensures a re-synchronization of the port selection.
