The DP83TC815-Q1 is an IEEE 802.3bw and Open Alliance (OA) compliant automotive qualified 100Base-T1 Ethernet physical layer transceiver. The device provides all physical layer functions needed to transmit and receive data over unshielded/shielded single twisted-pair cables with xMII interface flexibility.
The DP83TC815-Q1 integrates IEEE802.1AS / IEEE1588v2 to enable highly accurate time synchronization and hardware time stamping for time-sensitive, real-time controlled applications.
The DP83TC815-Q1 supports OA TC-10 low power sleep feature with wake forwarding for reduced system power consumption when communication is not required.
