KSZ8851SNLI-TR

The KSZ8851 is a single-port controller chip with a SPI or 8-/16-/32-bit non-PCI CPU interface.

Available in 32-/48-/128-pin packages, the KSZ8851 is for applications requiring cost-effective, high-throughput Ethernet connectivity in traditional embedded systems with MCUs or MPUs.

KSZ8851-16MLL: 8-/16-bit host bus, 48-pin package

KSZ8851-16/32MQL: 16-/32-bit host bus, 48-pin package (-16MQL) or 128-pin package (-32MQL)

The KSZ8851 is a single chip, mixed analog/digital device offering Wake-on-LAN technology for effectively addressing Fast Ethernet applications. It consists of a Fast Ethernet MAC controller, an 8-bit or 16-bit generic host processor interface and incorporates a unique dynamic memory pointer with 4-byte buffer boundary and a fully utilizable 18KB for both TX (allocated 6KB) and RX (allocated 12KB) directions in host buffer interface. The KSZ8851 is designed to be compliant with the appropriate IEEE 802.3u standards.

An industrial temperature-grade version of the KSZ8851 is also available. Physical signal transmission and reception are enhanced through the use of analog circuitry, making the design more efficient and allowing for lower-power consumption.

The KSZ8851 is designed using a low-power CMOS process that features a single 3.3V power supply with options for 1.8V, 2.5V or 3.3V VDD I/O. The device includes an extensive feature set that offers management information base (MIB) counters and CPU control/data interfaces with single shared data bus timing.

The KSZ8851 includes unique cable diagnostics feature called LinkMD®. This feature determines the length of the cabling plant and also ascertains if there is an open or short condition in the cable. Accompanying software enables the cable length and cable conditions to be conveniently displayed. In addition, the KSZ8851 supports Hewlett Packard (HP) Auto-MDIX thereby eliminating the need to differentiate between straight or crossover cables in applications.

KSZ8851是一款单端口控制器芯片，配有SPI或8/16/32位非PCI CPU接口。

KSZ8851提供32/48/128引脚封装，适用于在带MCU或MPU的传统嵌入式系统中要求经济高效、高吞吐量以太网连接的应用。

KSZ8851是一款单芯片、模拟/数字混合器件，提供LAN唤醒技术，可有效处理快速以太网应用。它由一个快速以太网MAC控制器、一个8位或16位通用主机处理器接口组成，集成了一个具有4字节缓冲边界的独特动态存储器指针，以及一个完全可利用的18KB，用于主机缓冲接口中的TX(分配6KB)和RX(分配12KB)方向。KSZ8851设计符合相应的IEEE 802.3u标准。

KSZ8851还提供工业温度级版本。通过使用模拟电路来增强物理信号的发送和接收，使设计更高效，并允许更低的功耗。

KSZ8851采用低功耗CMOS工艺设计，采用3.3V单电源供电，可选择1.8V、2.5V或3.3V VDD I/O。该器件包括丰富的功能集，可提供管理信息库(MIB)计数器和CPU控制/数据接口，具有单个共享数据总线时序。

KSZ8851包括称为LinkMD的独特电缆诊断功能。此功能决定了布线设备的长度，也确定了电缆中是否存在开路或短路情况。附带的软件能够方便地显示电缆长度和电缆状况。此外，KSZ8851支持惠普(HP)自动MDIX，因此无需在应用中区分直线电缆或交叉电缆。
