Problems solved by technology

[0003] The definition of COMe connector is expensive. In the actual test, due to the discontinuous signal impedance of the connector itself, the impedance of the entire high-speed signal link does not match, and the insertion loss of the high-speed signal is large.
The highest rate can only support 10Gbps, and the signal definition cannot meet new requirements

Abstract

The invention provides a COMe module based on a double-edge connector, the COMe module is installed on a buckle plate and inserted into a bottom plate customized for an application, the COMe module comprises a CPU, a CPLD and the double-edge connector, the double-edge connector comprises a first double-edge connector, a second double-edge connector and a third double-edge connector, the first double-edge connector comprises a first edge connector A and a first edge connector B, the first edge connector A comprises 60-bit interfaces A1-A60, and the first edge connector B comprises 60-bit interfaces B1-B60; and the second double-edge connector comprises a second edge connector C and a second edge connector D. According to the COMe module based on the double-edge connector, the cost of the connector is remarkably reduced, the problem that the impedance of the COMe connector is not matched is solved, the same package can be upgraded to 25Gbps, the PCB expansion capability is high, the signal definition expansibility is high, and the product upgrading requirement can be met.

Description

technical field [0001] The invention belongs to the technical field of COMe modules, in particular to a COMe module based on a double-edge connector. Background technique [0002] The COM Express standard was first published in 2005 by the PCI Industrial Computer Manufacturers Group (PICMG) and it seeks to provide a standardized module interface for several different target applications. COM Express is the form factor of a Computer on Module (COM), a highly integrated and compact PC that can be used like an integrated circuit component for design applications. Each COM Express module integrates core CPU and memory functions, general purpose I / O, USB, audio, graphics (PEG) and Ethernet. All I / O signals are mapped to two high-density low-profile connectors on the bottom of the module. COMe modules plug into backplanes that are usually application-specific. COM Express mezzanine modules can be upgraded to newer, backward compatible versions over time. COM Express is commonl...
