3 Description
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 timesensitive,
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.
