The DP83561-SP is a high reliability gigabit ethernet PHY designed for the high-radiation environment of space. The DP83561-SP is a low power, fully featured physical layer transceiver with integrated PMD sub-layers to support 10BASE-Te, 100BASE-TX and 1000BASE-T Ethernet protocols.

The DP83561-SP is designed for easy implementation of 10/100/1000 Mbps Ethernet LANs in extremely hostile environments. It interfaces directly to twisted pair media through an external transformer. This device interfaces directly to the MAC layer through Reduced GMII (RGMII) and MII.

The device is Radiation Hardened by Design (RHBD), fabricated by Texas Instruments using a CMOS process, and is available in 64-pin Ceramic Quad Flat Pack (CQFP) package, with a 11-mm × 11-mm body size (nominal).
