1 Features
3 Description
•
Open Alliance and IEEE 802.3bw 100BASE-T1
compliant
– Passes Level IV emissions with Integrated LPF
– TC-10 compliant with < 20μA sleep current
SAE J2962-3 EMC compliant
Configurable I/O voltages: 3.3 V, 2.5 V, and 1.8 V
MAC interfaces: MII, RMII, RGMII and SGMII
Optional separate voltage rail for MAC interface
pins (3.3 V, 2.5 V, 1.8 V)

ambient operating temperature
The DP83TC812-Q1 device is an IEEE 802.3bw-
compliant automotive PHYTER™ Ethernet physical
layer transceiver which can work with Unshielded
Twisted Pair cable. The PHY supports TC10 sleep
and wake features. It provides all physical layer
functions needed to transmit and receive data over
unshielded single twisted-pair cables. The device
provides xMII flexibility with support for standard MII,
RMII, RGMII, and SGMII MAC interfaces.The PHY
also integrates a low pass filter on the MDI side to
reduce emissions.

This device includes the Diagnostic Tool Kit, providing
an extensive list of real-time monitoring tools, debug
tools and test modes. Within the tool kit is the first
integrated electrostatic discharge (ESD) monitoring
tool. It is capable of counting ESD events on MDI
as well as providing real-time monitoring through the
use of a programmable interrupt. Additionally, the
DP83TC812-Q1 includes a pseudo random binary
sequence (PRBS) frame generation tool, which is
fully compatible with internal loopbacks, to transmit
and receive data without the use of a MAC. The
device is housed in a 6.00-mm × 6.00-mm, 36-pin
VQFN wettable flank package. This device is pin-2-
pin compatible with DP83TG720 (1000BASE-T1).
It is also form factor compatible with DP83TC811.
This would allow for a single PCB layout to be
used for DP83TC811, DP83TC812, DP83TC814, and
DP83TG720.
– ±8-kV HBM ESD for pins 12 and 13
– IEC61000-4-2 ESD classification level 4 for
pins 12 and 13: ±8-kV contact discharge
