Ethernet PHY transceiver enables use of unshielded twisted-pair cables

Designed for data communication over low-cost unshielded twisted-pair (UTP) cables, Microchip has introduced the KSZ8061 single-chip 10BASE-T/100BASE-TX automotive- and industrial-grade Ethernet physical-layer (PHY) transceiver. The device is the first of a new family based on the patented and programmable Quiet-WIRE enhanced EMC technology, providing reduced line emissions and superior receiver immunity performance. System reliability is also enhanced with Microchip's proven LinkMD+ advanced cable diagnostics in addition to an embedded signal-quality indicator for the dynamic monitoring of link error margins. For energy-efficient applications, Microchip's integrated EtherGREEN technology includes a unique Ultra Deep Sleep mode with signal-detect wakeup, which lowers standby power consumption to the sub-microampere range. With fast boot and linkup in less than 20mS, the KSZ8061 is ideal for applications where startup time is critical, such as automotive rear-view cameras. The KSZ8061 family is available with an extended temperature range of -40C to +105C for harsh-environment applications, including industrial sensor networks, robotics, building automation and avionics. This Ethernet PHY transceiver family provides support for both the MII and RMII processor interfaces, for easy integration with numerous processors, MCUs and SoCs. To enable functional and performance testing of the KSZ8061, the KSZ8061MNX Evaluation Board (KSZ8061MNX-EVAL) is also offered.
