3 Description

The DP83TC817S-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 DP83TC817S-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.

DP83TC817S-Q1 offers ingress classification to filter

the unwanted packets & supports WAN MACsec for

end-to-end security.

The DP83TC817S-Q1 integrates IEEE802.1AS /

IEEE1588v2 to enable highly accurate time

synchronization and hardware time stamping for

time-sensitive, real-time controlled applications, with

support for encrypted PTP packets.

The DP83TC817S-Q1 supports OA TC-10 low power

sleep feature with wake forwarding for reduced

system power consumption when communication is

not required.

The DP83TC817S-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.
