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.
