Problems solved by technology

The MDIO bus is affected by various factors during communication (performance limitations of the MDIO host itself, signal damage caused by MDIO transmission wiring, power interference, and other high-frequency signal interference), and it is easy to cause signal distortion at the MDIO terminal, resulting in board The MIDO bus of the device and the optical module fails, so it is very important to improve the reliability design of the MDIO bus transmission
[0003] The MDIO bus communication protocol does not limit whether the host sends data on the rising edge or the falling edge of the clock. If the MDIO slave uses a fixed clock edge to sample data, the timing may not meet the requirements and cause communication failures.
In addition, because the MDIO host is limited by its own IO port rate performance limitations, as well as signal damage caused by MDIO transmission lines, power supply and other high-frequency signal interference, the signal may be distorted at the MDIO slave terminal, which will also cause optical distortion. The communication between the module and the single board device is abnormal

Embodiment Construction

[0048] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the application more thorough and comprehensive.

[0049] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to an MDIO interface communication method and circuit. The method includes: receiving the MDC signal and MDIO data information sent by the MDIO master; determining the sampling moment of the MDIO slave according to the MDC signal; outputting an operation control signal according to the MDIO data information at the sampling moment of the MDIO slave ; Execute the operation process corresponding to the operation control signal. This application determines the sampling time of the MDIO slave according to the MDC signal, which effectively solves the problem that the clock edge inconsistency of the data sent by different MDIO master devices causes the sampling data error of the MDIO slave, and also avoids the interference of the transmission signal. The problems caused by distortion, the reliability and stability of MDIO interface communication can be improved by this method.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an MDIO interface communication method and circuit. Background technique [0002] The communication between the optical module and the optical network equipment board adopts MDIO (Management Data Input Output, management data input and output) bus interface. Since the optical module needs to be used in conjunction with various single-board devices, and the hardware environment of different single-board devices is different, the schemes for realizing the MDIO host are also different. The MDIO bus is affected by various factors during communication (performance limitations of the MDIO host itself, signal damage caused by MDIO transmission wiring, power interference, and other high-frequency signal interference), and it is easy to cause signal distortion at the MDIO terminal, resulting in board The MIDO bus of the device and the optical module fails, so it is very imp...
