The DP83TC818S-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 and TC10 Sleep-Wake functionality.

The DP83TC818S-Q1 integrates IEEE802.1AS / IEEE1588v2 hardware time stamping & fractional PLL, enabling highly accurate time synchronization. The fractional PLL enables frequency and phase synchronization of the wall clock (eliminating the need for external VCXO) and generation of a wide range of time synchronized frequencies needed for audio and other ADAS applications. The PHY also integrates IEEE 1722 CRF decode to generate Media clock and Bit Clock for AVB & other audio applications.

The DP83TC818S-Q1 integrates IEEE 802.1AE line rate security with authentication and optional encryption support to secure communication over the network. The DP83TC818S-Q1 supports up to 16 secure association (SA) channels with automatic SAK rollover and extended packet numbering support. DP83TC818S-Q1 offers ingress classification to filter the unwanted packets & supports WAN MACsec for end-to-end security.

The DP83TC818S-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.
