KSZ8051MNL集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

KSZ8051MNL属于集成电路（IC）的驱动器接收器收发器。由美国微芯科技公司制造生产的KSZ8051MNL驱动器，接收器，收发器该系列产品的主要功能是提供必需的硬件资源，以通过延长电缆或印制线进行通信。确切的功能会因所采用的通信协议而异，可能包括诸如瞬态抑制之类的功能，这些功能对于通信用途可能并非绝对必要，但对于可能的使用环境却是明智之选。

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.
