KSZ8041NL是单电源供电的10Base-T/100Base-TX物理层收发器,它可提供MII/RMII接口来收发数据。KSZ8041NL 是单电源供电的 10Base-T/100Base-TX 物理层收发器,它可提 MII/RMII 接口来收发数据。其独有的混合信号设计不但可以扩大发送信号的距离,与此同时还可以降低功耗。HP Auto MDI/MDI-X 提供了最强大的方案来消除了要在交叉线缆和直通线缆之间进行区分的需要。KSZ8041NL 是 代 表 着 新 一 层 级 别 特 性 和 性 能 的 收 发 器 , 且 对 用 于10BASE-T/100BASE-TX 应用的物理层收发器来说,它是极佳的选择。KSZ8041RNL 是 KSZ8041NL 的增强型 RMII 版本,它不要求使用 50MHz 的系统时钟。它使用 25MHz 的晶体来作为其输入基准时钟,并向 MAC 输出 50MHz 的 RMII 基准时钟。KSZ8041NL 和 KSZ8041RNL 的封装采用 32 引脚,无铅 MLF(符合 JDEC 标准的 QFN
封装)封装
