3 Description

The DP83TC816-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.

DP83TC816-Q1 integrates IEEE802.1AS /

IEEE1588v2 hardware time stamping and 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 and other audio applications.
