　　microchip公司的KSZ8061MN是单片10Base-T/100Base-TX以太网物理层收发器,能在不屏蔽双绞线(UTP)电缆上发送和接收数据.器件具有Quiet-WIRE®内部滤波以降低发送损耗,并提供MII接口,以直接和MII兼容的以太网MAC处理器和交换直接连接.主要用在工业控制,汽车在线诊断(OBD),汽车网关,照相和传感器网络和娱乐系统.本文介绍了KSZ8061MN主要特性,功能框图,KSZ8061 32-QFN评估板主要特性,框图,电路图,材料清单和PCB元件布局图.

　　The KSZ8061MN is a single-chip 10Base-T/100Base-TX Ethernet physical layer transceiver for transmission and reception of data over unshielded twisted pair (UTP) cable.

　　The KSZ8061MN features Quiet-WIRE® internal filtering to reduce line emissions. It is ideal for applications, such as automotive or industrial networks, where stringent radiated emission limits need to be met. Quiet-WIRE can use low-cost unshielded cable, where previously only shielded cable solutions were possible. The KSZ8061MN also features enhanced immunity to environmental EM noise.

　　The KSZ8061MN offers the Media Independent Interface (MII) for direct connection with MII-compliant Ethernet MAC processors and switches.

　　It is designed to exceed Automotive AEC-Q100 and EMC requirements, and features an extended temperature range of −40℃ to +105℃.

　　The KSZ8061MNX is supplied in a 32-lead, 5mm × 5mm QFN or WQFN package, while the KSZ8061MNG is in a 48-lead, 7mm × 7mm QFN package.

　　KSZ8061MN主要特性:

　　• Quiet-WIRE programmable EMI filter

　　• MII interface with MDC/MDIO management interface for register configuration

　　• On-chip termination resistors for the differential pairs

　　• LinkMD®+ receive signal quality indicator

　　• Fast start-up and link

　　• Low-power design with IEEE 802.3az Energy Efficient Ethernet support

　　• Ultra-Deep Sleep standby mode: CPU or signal detect activated.

　　• Loopback modes for diagnostics

　　• Programmable interrupt output

　　KSZ8061MN应用:

　　• Industrial control

　　• Vehicle on-board diagnostics (OBD)

　　• Automotive gateways

　　• Camera and sensor networking

　　• Infotainment

　　The KSZ8061 32-QFN Evaluation Board is designed to enable functional and performance testing of the KSZ8061MNX PHY. In addition to the KSZ8061 PHY, there is a second PHY – a KSZ8081. The KSZ8081 is a standard 10/100 Ethernet PHY. It is used here to provide a second line interface, for simple full-duplex traffic through the KSZ8061. This board is not intended for evaluation of the KSZ8081.
