Shenzhen Mingjiada Electronics Co., Ltd (Supply, Acquisition) Microchip Ethernet VSC8541XMV-02 and VSC8541XMV-05 Single-Port Gigabit Ethernet Copper PHY with GMII/RGMII/MII/RMII Interface

Description

The Microchip Ethernet PHY VSC8541XMV-02 and VSC8541XMV-05 devices are designed for space-constrained 10/100/1000BASE-T applications. They feature integrated line-side termination to save board space, reduce EMI, and improve system performance. In addition, integrated RGMII timing compensation eliminates the need for on-board delay lines.

The devices include a recovery clock output for synchronous Ethernet applications. Programmable clock squelch control suppresses undesirable clock propagation and helps prevent timing loops. Loop resiliency allows the PHY port to switch between master and slave timing references in 1000BASE-T mode without link interruption.

The following figure shows a high-level overview of a typical VSC8541-02 and VSC8541-05 application.
