3 Description
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.
