Abstract

A synchronizer circuit (300A) includes a first synchronizer (306A) having a first input (A) for receiving a signal associated with a first clock signal (CLK_A), a second input for receiving a second clock signal (CLK_B), and an output (Z1) for providing a synchronizer circuit output signal (SYNCH_O/P); a second synchronizer (308A) having a first input for receiving the signal associated with the first clock signal (CLK_A), a second input for receiving the second clock signal (CLK_B), and an output (Z2); a detection stage (310A) having a first input coupled to the output of the first synchronizer (306A) and to the output of the second synchronizer (308A), a second input for receiving the second clock signal (CLK_B), and an output (Z4); and a fault output stage (312A) having a first input (Z4) coupled to the detection stage (310A), a second input for receiving the second clock signal (CLK_B),, and an output for providing a fault output signal (FAULT_O/P).
