Out-of-band signal detection by host interfaces of storage modules

摘要

A host interface for a storage module may include an out-of-band (OOB) detector that is configured to detect receipt of an OOB signal using a clock signal. The clock signal may be generated by a clock generator that is activated using a counter. When an OOB signal is received, the counter may activate the clock generator. When no OOB signal is being received, the counter may wait for a predetermined time period before deactivating the clock generator.

1. An interface comprising:
a counter module configured to:
detect whether an out-of-band (OOB) signal is received by a physical layer of the interface;in response to detection of a presence of the OOB signal, send a control signal to activate or maintain activation of a clock generator, the clock generator configured to output a clock signal in response to being activated for detection of the OOB signal, wherein the clock generator is configured to generate the clock signal based on receipt of a single signal, the single signal being the control signal received from the counter module;in response to detection of an absence of the OOB signal, wait for a predetermined time period before deactivating the clock generator of the interface, the clock generator configured to cease output of the clock signal in response to being deactivated; and an OOB detector module configured to detect receipt of the OOB signal using the clock signal received by the clock generator.
