Field: Basic communication processes (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 16:
17. A system-on-chip comprising:
a processor; and
a host including a host interface with a clock modulator, wherein the host interface is configured to send a command and a main clock signal to an external device through a level shifter and receive a response to the command from the external device through the level shifter under control of the processor,
the clock modulator is configured to select one of the response and a feedback clock signal received from a level shifter as a selected value, and modulate a phase of the main clock signal based on the selected value to generate a modulated clock signal,
wherein the host is configured to send data to the external device through the level shifter synchronously with the main clock signal, and
wherein the host is configured to sample, synchronously with the modulation clock signal, data received from the external device through the level shifter.
