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.
