Microchip Releases New Ethernet PHY Transceiver


New KZS8061 10/100BASE-TX Ethernet Physical-Layer Transceiver Provides Reduced Line Emission and Superior Noise Immunity


Microchip has released the KSZ8061 single-chip 10BASE-T/100BASE-TX automotive- and industrial-grade Ethernet physical-layer transceiver, which is designed for data communication over low-cost Unshielded Twisted Pair (UTP) cables. It 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, along with 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.

“The KSZ8061 provides uniquely low emissions and high immunity over unshielded cabling, for automotive and industrial Ethernet network connectivity,” said Mitch Obolsky, vice president of Microchip's USB and Networking Group. “The result is a significant reduction in BOM costs, versus expensive shielded cables, while meeting the stringent EMC specifications for these applications. Additionally, the established Ethernet ecosystem provides a low total cost of ownership and multifaceted benefits.”

With fast boot and linkup in less than 20mS, the KSZ8061 is ideal for applications where startup time is critical, such as automotive rearview cameras. The KSZ8061 family is available with an extended temperature range of -40 to +105 degrees Celsius 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.
