Controlling method of connector, connector, and memory storage device

A connector, comprising:

• a first oscillator, configured to provide a first clock signal;
• a second oscillator, configured to provide a second clock signal, wherein a frequency shift of the first oscillator is smaller than a frequency shift of the second oscillator;
• a power management circuit, coupled to the first oscillator and the second oscillator, configured to receive the first clock signal and the second clock signal, correct a detection window information corresponding to the second clock signal according to the first clock signal and the second clock signal, and turn off the first oscillator;
• and
• a checking circuit, coupled to the power management circuit and the second oscillator, configured to receive a signal stream, wherein the signal stream comprises a first signal,
• wherein the checking circuit is configured to generate a detection window according to the corrected detection window information and the second clock signal and determine whether the first signal is a burst signal according to the detection window.

A memory storage device, comprising:

• a connector, configured to couple to a host system and receive a signal stream from the host system, wherein the signal stream comprises a first signal;
• a rewritable non-volatile memory module, comprising a plurality of physical erasing units;
• and
• a memory controller, coupled to the connector and the rewritable non-volatile memory module,
• wherein the connector comprises:
• a first oscillator, configured to provide a first clock signal;
• a second oscillator, configured to provide a second clock signal, wherein a frequency shift of the first oscillator is smaller than a frequency shift of the second oscillator;
• a power management circuit, coupled to the first oscillator and the second oscillator, configured to receive the first clock signal and the second clock signal, correct a detection window information corresponding to the second clock signal according to the first clock signal and the second clock signal, and turn off the first oscillator;
• and
• a checking circuit, coupled to the power management circuit and the second oscillator, configured to receive the signal stream, generate a detection window according to the corrected detection window information and the second clock signal, and determine whether the first signal is a burst signal according to the detection window.
