Abstract
A glitch detection circuit is described for detecting a glitch on a strobe signal transmitted over a single strobe interface. The glitch detection circuit includes a first input terminal to receive a single strobe signal and a second input terminal to receive a protocol control signal. The glitch detection circuit uses a double edge detection circuit to detect two consecutive rising or falling edges on the strobe signal. The double edge detection circuit becomes initialized by an initializing circuit each time the logical state of the control signal changes from a first state to a second state. The glitch detection circuit is configured to output a glitch detection signal when two consecutive rising or falling edges are detected by the double edge detection circuit before being initialized by the initializing circuit.
