3 Description
The DP83TG720R-Q1 device is an IEEE 802.3bp
and Open Alliance compliant automotive Ethernet
physical layer transceiver. It provides all physical layer
functions needed to transmit and receive data over
unshielded/shielded single twisted-pair cables. The
device supports RGMII for interfacing with a MAC.
– EMC immunity Class-IV compliant for UTP
(unshielded twisted pair)
Integrated LPF on MDI pins

•
MAC Interface: RGMII
Supported I/O voltages: 3.3 V, 2.5 V, and 1.8 V
Pin compatible with TI's 100BASE-T1 PHY
– Single board design for 100BASE-T1 and
1000BASE-T1 with required BOM change
Power savings features:
– standby and sleep
– local and remote wake-up
Diagnostic tool kit
– high accuracy temperature monitor
– voltage monitor
– ESD event monitor
– Data throughput calculator : inbuilt MAC packet
generator, counter and error checker
– link quality monitoring
– cable open and short fault detection
– loopback modes
DP83TG720 is compliant to Open Alliance EMC and
interoperable specifications over unshielded twisted
cable. DP83TG720 is pin-2-pin compatible to TI's
100Base-T1 PHY enabling design scalability with
single board for both speeds.This device offers the
Diagnostic Tool Kit, with 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 both the xMII and MDI
as well as providing real-time monitoring through
the use of a programmable interrupt. Additionally,
the DP83TG720R-Q1 includes a data generator and
checker tool to generate customizable MAC packets
and check the errors on incoming packets.This
enables system level datapath tests/optimizations
without dependency on MAC.
