3 Description

The DP83TG721-Q1 is an IEEE 802.3bp and

Open Alliance compliant automotive 1000Base-T1

Ethernet physical layer transceiver. The DP83TG721-

Q1 provides all physical layer functions needed to

transmit and receive data over unshielded/shielded

single twisted-pair cables. The device provides xMII

flexibility with support for RGMII and SGMII MAC

interfaces.

DP83TG721-Q1 supports OA TC10 low power sleep

feature (with wake forwarding) to reduce system

power consumption when communication is not

required. This device offers the Diagnostic Tool Kit,

with an extensive list of real-time monitoring tools,

debug tools and test modes.

DP83TG721-Q1 integrates IEEE 1588v2/802.1AS

hardware time stamping & fractional PLL enabling

highly accurate time synchronization. The fractional

PLL enables frequency/phase synchronization of the

Wall Clock eliminating need for external VCXO

and generating wide range of time synchronized

frequencies needed for Audio, Video and other ADAS

applications.

DP83TG721-Q1 also integrates IEEE 1722 CRF

decode to generate Media Clock (wall clock

synchronized) for AVB & other Audio standards.

The DP83TG721-Q1 is also capable of generating

FSYNC/SCLK (wall clock synchronized) for I2S/TDM8

interface needed for audio applications.

The DP83TG721-Q1 is compatible to TI's 100BASET1

PHYs and 1000BASE-T1 PHYs enabling design

scalability with single board for both speeds.
