TI公司的TLK111是一款单端口以太网10Base-T和100Base TX 信号收发器芯片,内嵌以双绞线为传输媒介的标准以太网所有物理层接收和发送数据的功能。此外,通过外部增加光端收发器器件可以实现100Base-FX信号收发功能。该芯片通过MII和RMII接口与内部MAC控制器进行数据交互,供电可采用3.3V单独电源供电或采用减少功率的3.3V和1.55V组合方式供电。本文首先介绍芯片的简介、特性、内部框图及应用领域,并给出相应设计方案的设计原理图及元器件列表。

The TLK111 is a single-port Ethernet PHY for 10Base-T and 100Base TX signaling. This device integrates all the physical-layer functions needed to transmit and receive data on standard twisted-pair cables. Additionally, the TLK111 supports 100Base-FX signaling via an external optical transceiver. The device supports the standard Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) for direct connection to a Media Access Controller (MAC).

The TLK111 is designed for power-supply flexibility, and can operate with a single 3.3V power supply or with combinations of 3.3V and 1.55V power supplies for reduced power operation.
