Scannable synchronizer having a deceased resolving time

The present invention provides a synchronizer for receiving an incoming data signal of a first clock domain and for outputting a data signal of a second clock domain. The synchronizer comprises an input stage, a master latch, a transfer stage and a slave latch. The input stage receives the data signal of the first clock domain and outputs the data signal to the master latch when the input stage is clocked with a master clock signal. The master latch stores the data signal at a storage node of the master latch. The master latch has a resolve time associated with it during which the master latch seeks to resolve the data signal to a logic 0 or a logic 1. The transfer stage transfers the data signal stored in the master latch to the slave latch when the transfer stage is clocked with a slave clock signal.
