DP83TG721R-Q1

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 and 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 and 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 100BASE-T1 PHYs and 1000BASE-T1 PHYs enabling design scalability with single board for both speeds.
