KSZ8091RNBIA-TR

The KSZ8091 is a single-supply 10Base-T/100Base-TX Ethernet physical-layer transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable. The KSZ8091 is a highly-integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs, integrating a low-noise regulator to supply the 1.2V core and by offering a flexible 1.8/2.5/3.3V digital I/O interface.

The KSZ8091MNX and KSZ8091MLX offer the Media Independent Interface (MII), while the the KSZ8091RNx offer the Reduced Media Independent Interface (RMII) for direct connection with MII/RMII-compliant Ethernet MAC processors and switches.

Wake-on-LAN (WOL) provides a mechanism for the KSZ8091 to wake up a system that is in standby power mode. The KSZ8091 provides diagnostic features to facilitate system bring-up and debugging in production testing and in product deployment. Parametric NAND tree support enables fault detection between KSZ8091 I/Os and the board. Microchip's LinkMD® TDR-based cable diagnostics identify faulty copper cabling.

The KSZ8091RNA and KSZ8091RND are available in a 24-pin (4mm x 4mm) QFN package. The KSZ8091MNX and KSZ8091RNB are available in a 32-pin, lead-free QFN packages. The KSZ8091MLX is available in a 48-pin (7mm x 7mm) LQFP package.

KSZ8091是一款单电源10Base-T/100Base-TX以太网物理层收发器，用于通过标准CAT-5非屏蔽双绞线(UTP)电缆发送和接收数据。KSZ8091是高度集成的PHY解决方案。它将片内端接电阻用于差分对，集成一个低噪声调节器为1.2V内核供电，并提供灵活的1.8/2.5/3.3V数字I/O接口，从而降低电路板成本并简化电路板布局。

KSZ8091MNX和KSZ8091MLX提供媒体独立接口(MII ),而KSZ8091RNx提供简化的媒体独立接口(RMII ),用于直接连接符合MII/RMII标准的以太网MAC处理器和交换机。

局域网唤醒(WOL)为KSZ8091提供了一种唤醒处于待机电源模式的系统的机制。KSZ8091提供诊断功能，有助于生产测试和产品部署中的系统启动和调试。参数NAND树支持实现ksz 8091 I/o和电路板之间的故障检测。Microchip基于LinkMD TDR的电缆诊断可识别有故障的铜缆。

KSZ8091RNA和KSZ8091RND采用24引脚(4毫米x 4毫米)QFN封装。KSZ8091MNX和KSZ8091RNB采用32引脚无铅QFN封装。KSZ8091MLX采用48引脚(7mm x 7mm) LQFP封装。
