The TJA1101 can be configured as Master or Slave and can be operated in Managed or Autonomous modes. In Autonomous operation, the PHY automatically enters Normal mode and activates the link on power-on without further interaction with a host controller. The TJA1101 can operate from a single 3.3V supply. This PHY also provides the option to switch off the internal 1.8V LDO and operate from a high efficiency external 1.8V supply. The OM14500/TJA1101JP evaluation board provides the single 3.3V supply (internal 1.8V enabled) to simplify the evaluation.
