3 Description

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.
