Clock management system in uTCA system and method thereof

Abstract

The invention discloses a clock management system in a uTCA system and a method thereof. The system comprises a clock management device and an SERDES clock generation unit, wherein, the clock management device comprises a reference source clock selection unit, a clock source generation unit and a clock source drive unit, the reference source clock selection unit selects a clock source from a plurality of received clock sources as a reference clock source; the clock source generation unit generates a clock source synchronous with the reference clock source according to the received reference clock source; the clock source drive unit carries out level translation on the clock source received from the clock generation unit, and transmits the clock source to the SERDES clock generation unit; and the SERDES clock generation unit carries out frequency conversion on the clock source received from the clock source drive unit, and generates desired SERDES clock. The system and the method help reduce the realization difficulty of hardware circuits, PCB area of MCH units and the cost.

Description

technical field [0001] The invention relates to the technical field of uTCA systems, in particular to a clock management system and method in the uTCA system. Background technique [0002] MicroTCA (also known as uTCA) is the PCI Industrial Computer Manufacturers Association ( ) is a new open standard currently under development. Compared with ATCA, the uTCA architecture is smaller in size and more suitable for base station side equipment. It is an open standard communication service platform promoted by Intel and others. Its purpose is to hope that based on a unified hardware architecture, different equipment manufacturers Provide communication boards, and finally a complete set of communication equipment will be integrated by the system manufacturer. [0003] Such as figure 1 as shown, figure 1 It is a structure diagram of a uTCA system in the prior art. In a uTCA system, a system consists of chassis, PM (power module, Power Module), MCH (uTCA CarrierHub, management ...

AI Technical Summary

Problems solved by technology

[0008] In view of the above analysis, the present invention aims to provide a clock management system and method in a uTCA system to solve the problems of uTCA architecture redundancy and deterioration of clock performance on the MCH single board existing in the prior art
