100BASE-TX 2ch Ethernet PHY
MegaChips has developed a 100BASE-TX compliant 2-channel Ethernet PHY device. This is designed for use in industrial applications such as FA, highly focusing on noise immunity like ESD.
Features
- 2-Port 100BASE-TX compliant Ethernet PHY
2ch of MDI IF are incorporated for fieldbus use in FA control and other applications. Compared to the use of two 1ch products, it is possible to reduce the board area and BOM cost. - Single power operation
On-board LDO for the internal power supply operates externally with a single 3.3V power supply. - Wide range of operating temperature
Operating temperatures range from -40°C ~ +125°C.
