Problems solved by technology

[0004] The disadvantages of the existing technology are: the data is written and exported multiple times, which makes the calculation complicated, and the additional external EEPROM increases the cost. At the same time, the UX3320 has the problem of misjudging the read and write operations of the external EEPROM.

Embodiment Construction

[0013] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0014] Such as figure 1 as shown,

[0015] The circuit based on the optical drive UX3320 without external EEPROM includes a MAC module circuit, a PMD module circuit and a GPON BOSA module circuit based on the UX3320 component. The MAC module circuit is connected to the PMD module circuit, and the PMD module circuit is connected to the GPON BOSA module circuit. The FLASH on the BOB stores the data required by the UX3320, and the main IIC of the UX3320 is externally connected to a pull-up resistor to VCC.

[0016] After the UX3320 is powered on, the data in the FLASH is read by the MAC and imported into the UX3320 RAM; the UX3320RAM data is divided into several areas, specifically including A0 Lower, A0 Upper, A2 Lower, Table0, LUT4, LUT5, L...

Abstract

The invention discloses a circuit based on a light-driven UX3320 plug-in-free EEPROM. The circuit comprises an MAC module circuit based on a UX3320 assembly, a PMD module circuit and a GPON BOSA module circuit, wherein the MAC module circuit is connected with the PMD module circuit, and the PMD module circuit is connected with the GPON BOSA module circuit. The circuit is characterized in that datarequired by UX3320 is stored by a FLASH on a BOB, and a main IIC of the UX 3320 is externally connected with a pull-up resistor to a VCC. The problem that a plug-in EEPROM is needed for storing datain a traditional MAC work mode is solved, and the data required by the UX 3320 is stored in the flash on the BOB, so that the cost of the EEPROM is reduced; in addition, the plug-in EEPROM is removed,and misjudgment of read-write operations of the UX3320 on the plug-in EEPROM are avoided.

Description

technical field [0001] The invention relates to the field of MAC address processing, in particular to a circuit based on an optical drive UX3320 without an external EEPROM. Background technique [0002] MAC (Media Access Control or Medium Access Control) address, translated as media access control, or called physical address, hardware address, is used to define the location of network devices. In the OSI model, the third layer of the network layer is responsible for the IP address, and the second layer of the data link layer is responsible for the MAC address. So a host will have a MAC address, and each network location will have an IP address unique to it. [0003] For now, in the traditional MAC working mode, data import requires UX3320 external EEPROM for storage, and then write data from external EEPROM to UX3320 RAM. [0004] The disadvantages of the existing technology are: the data is written and exported multiple times, which makes the calculation complicated, and ...
