LAN8670/1/2 10BASE-T1S Ethernet PHY Transceivers Microchip Technology LAN8670/1/2 10BASE-T1S Ethernet PHY Transceivers are compact, low-power, single-port 10BASE-T1S Ethernet physical layer transceivers. The devices are designed according to the IEEE Std 802.3cg-2019™ specification. The device provides 10Mbit/s half-duplex transmit and receive capability over a single-balanced pair medium like Unshielded Twisted Pair (UTP) cable. The LAN8670/1/2 is designed for use in applications requiring an extended temperature range (-40°C to +125°C). The device is also compliant with industrial EMC and EMI requirements. The single power supply and simple analog front end simplify its integration into small form factor applications.
