Abstract

The invention provides an interface device and electronic equipment, belongs to the technical field of network equipment, and solves the technical problem that a golden finger region cannot be suitable for next-generation pulse amplitude modulation technology transmission due to over-high crosstalk. The interface device comprises golden finger contact pieces, grounding pin contact pieces and an insulating layer, wherein the golden finger contact pieces and the grounding pin contact pieces are arranged on the insulating layer, and the grounding pin contact pieces and the golden finger contact pieces are arranged at intervals; and the grounding pin contact pieces are provided with anti-crosstalk hollow patterns.

Description

technical field [0001] The invention relates to the technical field of network equipment, in particular to an interface device and electronic equipment. Background technique [0002] With the increasing demand for cloud computing and cloud storage, the board transmission interface has also been upgraded from the original non-return zero (NRZ) transmission to the pulse-amplitude modulation (PAM4) mechanism . Among them, the PCIe (peripheral component interconnect express, high-speed serial computer expansion bus standard) interface is the main interface for boards and cards. The next-generation PCIe Association has also decided to change the modulation from NRZ to PAM4. However, the PAM4 interface has more stringent requirements for signal crosstalk than NRZ. The traditional non-return-to-zero code modulation method, when the transmission speed is 28Gbps (switching bandwidth), its unit interval time is 36ps (picosecond, picosecond), and the pulse amplitude modulation At 28G...
