DP83TD510ERHBR

DP83TD510ERHBR is a Texas Instruments 10/100 Mbps Ethernet PHY transceiver. It provides the physical layer to connect a MAC/controller to an Ethernet RJ-45 network.
Key points
- IEEE 802.3 10/100BASE-T compatible PHY with auto-negotiation for speed and duplex.
- Interfaces to the MAC via a digital interface (MII and/or RMII variants are commonly supported by TI PHYs; check datasheet for exact option).
- Management via MDIO/MDC and standard status/diagnostic signals.
- Features like Auto-MDI/MDIX, loopback/test modes, and low-power options are typical.
- Designed for embedded and industrial use with RoHS-compliant packaging (HBR suffix indicates a specific TI package/reel option).
Typical uses
- Microcontroller/SoC-based designs needing a PHY to an RJ-45 connector.
- Small/industrial Ethernet endpoints, gateways, or networked sensors.
Notes
- The suffix HBR mainly denotes packaging/reel options; electrical specs are defined in the datasheet. Always verify the exact interface options (MII/RMII), supply voltages, and pinout for your board.
- If you need full details, consult the DP83TD510ERHBR datasheet and application notes.

Key features of DP83TD510ERHBR (TI Gigabit PHY):
