Product Overview
The DP83TD510E is a Texas Instruments 10Base-T1L Ethernet PHY for IEEE 802.3cg Single Pair Ethernet links. It operates at 10 Mbps and supports cable reach beyond 2000 m in both 1-V p2p and 2.4-V p2p operating modes. Transmit and receive PMD amplitude compatibility covers 2.4 V p2p and 1 V p2p configurations.
Host interface support includes MII, RMII master and slave, RGMII, RMII master low-power 5-MHz mode, and RMII back-to-back operation. Clocking options include 25 MHz and 50 MHz clock output behavior, 25 MHz ±50 ppm reference input for MII and RMII master operation, and 50 MHz ±50 ppm CMOS-level reference input for RMII slave mode.
Power options include single 3.3 V supply operation or dual-supply operation for lowest power dissipation. VDDIO supports 1.8 V, 2.5 V, or 3.3 V, with a 1.0 V DVDD option and VDDA operation at 3.3 V or 1.8 V depending on p2p mode. The 32-pin QFN/VQFN package supports compact assembly for Ethernet PHY designs requiring cable diagnostics, EMC immunity, and -40°C to 105°C operation.
