The DP83TD535-Q1 is 10BASE-T1S OA TC-14 compliant PMD transceiver with MDC/MDIO management port and direct VBAT supply connection. This device provides full analog front end functionality while relying on the host system for MAC, digital PHY, and management functions. This solution, similar to the CAN transceiver approach, features a simple and cost effective 3-pin clock-less interface between the host controller and the PMD transceiver chip. The device supports 10Mbps multi-drop or point-to-point half-duplex communication over unshielded twisted pair cables with extended common mode voltage (CMV) tolerance. The device communicates to a host controller or switch using OA-3pin interface. The host must have the 10BASE-T1S digital PHY incorporated.
Additionally MDC/MDIO pins allow host-independent configurations, enhanced diagnostics, and flexible power-domain design while maintaining full compatibility with the OA3-pin PMD digital interface in the MCU.
The DP83TD535-Q1 incorporates TC10 wake/sleep features to enable efficient system-level power consumption. The device supports remote wake-up over the Ethernet data line. When a wake-up event is detected, the DP83TD535-Q1 initiates system start-up by driving INH high.
The DP83TD535-Q1 is equipped with diagnostic features such as cable fault detection, undervoltage and overtemperature monitoring to streamline system development and maintenance.
