The DP83TC817-Q1 device is an IEEE 802.3bw automotive Ethernet physical layer transceiver. The device provides all physical layer functions needed to transmit and receive data, and xMII interface flexibility. DP83TC817-Q1 is compliant to Open Alliance EMC and interoperable specifications over unshielded single twisted-pair cable. DP83TC817-Q1 supports OA TC-10 low power sleep feature with wake forwarding for reduced system power consumption when communication is not required.

The DP83TC817-Q1 integrates IEEE 802.1AE line rate security with authentication and optional encryption support, to secure communication over the network. The PHY supports up to 16 secure association (SA) channels with automatic SAK rollover and extended packet numbering support. DP83TC817-Q1 offers ingress classification to filter the unwanted packets & supports WAN MACsec for end-to-end security.

DP83TC817-Q1 also integrates 1588v2/802.1AS to enable highly accurate time synchronization and hardware timestamping for ADAS applications. DP83TC817-Q1 also offers precise time stamping and synchronization with encrypted PTP packets.

DP83TC817-Q1 is footprint compatible to TI’s 100BASE-T1 PHYs and 1000BASE-T1 PHYs enabling design scalability with a single board for different speeds and features.
