Circuit board for connectors

Abstract

A circuit board designed for high-frequency and high-speed data transmission is disclosed. The circuit board features a compact layout for differential pair circuits with less elevation occupied on one end, resulting in a circuit board shaped with a narrow side and a wide side. The narrow side is adapted for electrical coupling with an ASIC substrate, while the wide side is adapted for electrical coupling with at least one Ethernet port. This circuit board creates an extremely short-range (XSR) interface between the ASIC and the Ethernet port.
