National Semiconductor recently made available its popular DP83848 family of Phyter application-specific 10/100 physical layer Ethernet transceivers in new, very tiny 6 x 6 mm x 0,8 mm packages. The family includes the only commercially available Ethernet transceiver in an extreme temperature range for use in harsh environments such as motor control, factory automation and security systems.
The company's Phyter family of extreme, industrial and commercial-environment Ethernet transceivers are claimed to be the first to address the expansive, unique needs of embedded-design engineers who are developing products that require network connectivity. In addition, the DP83848 family enables engineers to migrate from legacy technologies such as RS232, RS485 and proprietary networks to 802.3 Ethernet.
The DP83848H extreme, DP83848T industrial and DP83848M commercial, in small LLP packaging enable flexible system partitioning in size-constrained applications, such as ultra-small motor drives and rotary encoders. In addition, the transceivers allow for the use of cost-effective series capacitors rather than bulky node side transformers.
The Phyter extreme DP83848H (-40 to 125°C), and industrial DP83848T (-40 to 85°C), transceivers also offer ESD protection of 4000 V, and up to 137 metres of cable reach. Both have IEEE 802.3 specification compliance guaranteed. These devices are well-suited for implementing Ethernet in transportation, building automation and security applications.
The Phyter commercial DP83848M transceiver addresses the requirements of embedded developers networking their devices for the home or high end peripherals. This device offers an optimised feature set for these applications, including Auto-MDIX and assured performance through IEEE 802.3u specification compliance, UNH interoperability certification, and up to 137 metres of cable reach.
