Microchip Technology Inc. recently announced the availability of the LAN8840 and LAN8841 Gigabit Ethernet transceiver devices compliant with the Precision Timing Protocol IEEE® 1588v2 standard. The LAN8840/41 Ethernet devices are enabled with Linux® drivers and deliver flexible Ethernet speed options including 10BASE-T, 10BASE-Te, 100BASE-TX and 1000BASE-T.
The LAN8840/41 devices can facilitate critical packet prioritization by providing high-speed time stamping that is then relayed between the various components to determine network latencies, accommodate for those latencies, and synchronize time amongst all connected devices. This functionality is key for process automation applications that require precise control production systems such as robotics, distributed sensors and cooling and mixing systems. Designed with robust applications in mind, the LAN8840/41 devices can withstand extended industrial temperatures ranging from -40°C to +105°C.
“The new LAN8840/41 single-port transceivers round out our Time Sensitive Networking offering by providing the connectivity for end nodes in process automation applications,” said Charles Forni, vice president of the USB and networking business unit at Microchip. “These devices complement our existing Ethernet portfolio, providing our customers with an end-to-end network solution of components, development tools and support from Microchip.”
To help companies achieve sustainability goals by reducing a network’s power consumption, the LAN8840/41 offers features like Wake-on-LAN (WoL) and energy-detect power-down mode.
Additionally, Energy-Efficient Ethernet (EEE) delivers low-power idle and clock stoppage modes for optimal power performance.
Microchip is an established supplier of industrial-grade networking solutions, offering a broad portfolio of robust and highly integrated products. The new LAN8840/41 devices are well suited for markets with applications requiring accurate and precise time stamping, such as gas and chemical processing, electrical distribution, and currency trade systems which must be proven to be in sync with the National Institute of Standards and Technology (NIST) for Universal Coordinated Time (UTC) within one millisecond or finer increments.
The LAN8840 (48 QFN) and LAN8841 (64 WQFN) are now available in high-volume production. Pricing starts at $2.78 in 10,000-piece quantities. For more information, please visit https://www.microchip.com/en-us/products/high-speed-networking-and-video/ethernet/ethernet-phys.
