Embodiment Construction

[0019] Certain terms are used in the description and claims to refer to particular elements. It should be understood by those skilled in the art that manufacturers may refer to the same element by different terms. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described in the text that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. .

[0020] Please refer to figure 2 , figure 2 It is a f...

Abstract

The invention provides a signal identification method and a signal identification device. The signal identification method comprises receiving a signal; continuously sampling the signal through a clock rate which is generated through an annular oscillator to generate a plurality of sampling values; counting the length of every sampling signal, wherein the sampling signals in the plurality of sampling values are identical in continuous numerical values; identifying signal contents according to the length of the plurality of the sampling signals. The signal identification device comprises a receiving circuit which is used for receiving the signal, the annular oscillator which is used for generating the clock rate, a sampling circuit which is used for continuously sampling the signal according to the clock rate to generate the plurality of sampling values, a counter which is used for counting the length of every sampling signal and a judging unit which is used for identifying the signal contents according to the length of the plurality of sampling signals, wherein the sampling signals in the plurality of sampling values are identical in continuous numerical values.

Description

technical field [0001] The embodiments disclosed in the present invention are related to signal identification, especially a ring oscillator (ring oscillator) instead of a phase-locked loop (Phase Lock Loop, PLL) to generate a clock, and sample a signal according to the clock And a method for identifying the content of the signal and related circuits are provided. Background technique [0002] In recent years, Solid State Drive (SSD) has gradually consolidated its position in the storage media market, and is widely used in personal computers and various mobile devices, while Serial Advanced Technology Attachment (Serial Advanced Technology Attachment, SATA) interface is currently the mainstream interface of solid-state drives. Due to the increasingly urgent need for various devices to reduce power consumption, the SATA device specification defines a sleep mode (slumber mode) especially for SATA devices, which is useful for long-term idle devices. Apps are especially import...
