SMSC’s LAN8700 and industrial temperature-rated LAN8700i transceivers with HP Auto-MDIX* support are designed for high-performance Ethernet applications. Both devices leverage flexPWR™ technology, which provides a flexible power management architecture that can be configured to optimize total system power for customers who require a smaller footprint and lower power solution without compromising on features. An integrated 3.3V to 1.8V regulator can be enabled for single supply operation, or disabled to save power if an external 1.8V supply is available. Additional system power can be saved by scaling the I/O voltage to the lowest voltage possible within the configurable 1.6V to 3.6V range. Many of today’s higher performance ASICs, SoCs and FPGAs have migrated to aggressive process geometries which require lower I/O voltages. The LAN8700 and LAN8700i also feature the industry’s best ESD performance (± 8kV HBM, ± 8kV contact and ± 15kV air discharge IEC), based on independent lab test results.**
