Methods and circuits for controlling multicycle path in serializer interface

A circuit for controlling a multicycle data path in a serializer interface, comprising:

• serializer delay replica circuitry configured to:
• determine a desired delay window of a multicycle data path in a serializer interface by sampling at least one step response at the serializer delay replica circuitry at an edge of a first clock signal and a gating signal, in response to synchronizing a second clock signal with a negative edge of the first clock signal;
• configure a polarity of a latch in a subsequent serializer of a serializer chain based on the determined desired delay window;
• and
• control the multicycle data path in the serializer interface based on the configured polarity of the latch in the subsequent serializer of the serializer chain.

A circuit for controlling a multicycle data path in a serializer interface, comprising:

• serializer delay replica circuitry configured to:
• detect whether a delay in a multicycle data path in a serializer interface is less than a desired value;
• and
• control a direction of a clock of a latch for the multicycle path in the serializer interface based on the detected delay.
