DP83TC818S-Q1

The DP83TC818S-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. DP83TC818S-Q1 is compliant to Open Alliance EMC and interoperable specifications over unshielded single twisted-pair cable. DP83TC818S-Q1 supports OA TC-10 low power sleep feature with wake forwarding for reduced system power consumption when communication is not required.

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.

DP83TC818S-Q1 integrates IEEE 1588v2/802.1AS 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.
