ATCA-based (advanced telecommunications computing architecture based) device and clock signal synchronization method thereof

Abstract

The invention discloses an ATCA-based (advanced telecommunications computing architecture based) device. The device is characterized in that a first connecting unit is arranged at one end, close to a second connecting portion, of a third connecting portion; a front plug board is provided with first slots; a back board is provided with second slots; one end of the first connecting unit is fitly inserted into the corresponding first slot; the other end of the first connecting unit is fitly inserted into the corresponding second slot; the second slots are in signal connection with a clock circuit of the front plug board through the first connecting unit and the first slots; the first connecting unit receives a clock signal of the front plug board through the first slots and transmits the received first signal to the second slots. The invention further discloses a clock signal synchronization method of the ATCA-based device; through the use of the ATCA-based device and the clock signal synchronization method, clock circuit signals of the front plug board is transmitted to the corresponding second slot in a point-to-point manner, clock signal quality is improved, and the application of high-quality clock signals is satisfied.

Description

technical field [0001] The invention relates to the field of ATCA architecture, in particular to a device based on the ATCA architecture and a method for synchronizing clock signals thereof. Background technique [0002] ATCA (Advanced Telecom Computing Architecture, Advanced Communication Computing Architecture) is a cost-effective, modular-based, compatible and scalable hardware architecture for converged communication and data network applications. [0003] As a platform mainly oriented to packet applications, ATCA adopts a bus-type clock structure, only defines 6 groups of clock signals, and has weak support for clock signal synchronization. [0004] At the same time, because ATCA adopts a bus-type clock structure, the driving and receiving of clock signals are all performed on the same bus, that is, clock synchronization is realized through clock bus sharing. Although the bus-type clock structure simplifies the design, due to the influence of the load on the bus, the q...

Problems solved by technology

Although the bus-type clock structure simplifies the design, due to the influence of the load on the bus, the quality of the clock signal is reduced, and it cannot provide a high-quality clock signal, so the platform cannot meet the application of high-quality clock signals
