ST802RT1B集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

ST802RT1B属于集成电路（IC）的驱动器接收器收发器。由意法半导体集团制造生产的ST802RT1B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。

Description

The ST802RT1x is a high-performance fast Ethernet physical layer interface for 10Base-T, 100Base-TX and 100Base-FX applications. It is designed using advanced CMOS technology to provide MII and RMII interfaces for easy attachment to 10/100 media access controllers (MAC). The ST802RT1x supports the 100BaseTX of IEEE802.3u and 10Base-T of IEEE802.3i and 100Base FX of IEEE 802.3u (B version only). The ST802RT1x supports both half-duplex and full-duplex operation at 10 and 100 Mbps operation. Its operating mode can be set using auto-negotiation, parallel detection or manual control. It allows for the support of auto negotiation functions for speed and duplex detection. The automatic MDI / MDIX feature compensates for the use of a crossover cable. With auto MDIX, the ST802RT1x automatically detects what is on the other end of the network cable and switches the TX & RX pin functionality accordingly.
