KSZ8051MNL屬于集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器。由微芯科技股份有限公司制造生產(chǎn)的KSZ8051MNL驅(qū)動(dòng)器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過(guò)延長(zhǎng)電纜或印制線進(jìn)行通信。確切的功能會(huì)因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類(lèi)的功能，這些功能對(duì)于通信用途可能并非絕對(duì)必要，但對(duì)于可能的使用環(huán)境卻是明智之選。

General Description

The KSZ8051 is an AEC-Q100 standard qualified single-supply 10BASE-T/100BASE-TX Ethernet physical-layer transceiver.

The KSZ8051 is a highly integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs and by integrating a low-noise regulator to supply the 1.2V core.

The KSZ8051MNL offers the Media Independent Interface (MII) and the KSZ8051RNL offers the Reduced Media Independent Interface (RMII) for direct connection with MII-/RMII-compliant Ethernet MAC processors and switches.
