GPY212 is a single-port 2.5Gbit/s Ethernet PHY with PTP (IEEE1588v2) and MACsec support.


The device supports the 2.5GBASE-T, 1000BASE-T, 100BASE-TX and 10BASE-Te modes of the IEEE802.3 standard and provides great interoperability for high data rate connections as well as for connections with legacy 1000BASE-T, 100BASE-TX and 10BASE-T devices.


GPY212 is connected to the MAC of an SoC or switch with a low pin-count SGMII+/SGMII interface. The SGMII+/SGMII interface supports 10M, 100M, 1G and 2.5Gbit/s rates or IEEE802.3x rate adaptation using pause frames.


GPY212 supports Energy-Efficient Ethernet (EEE) in the 2.5GBASE-T, 1000BASE-T and 100BASE-TX modes to reduce power consumption during periods of low traffic. Additional power saving can be achieved by using the Wake-on-LAN (WoL) functionality and the ultra-low power mode.


GPY212 supports MACsec (IEEE 802.1AE) point-to-point wire speed encryption and decryption for MAC layer data security and the Precision Time Protocol (PTP, 1588v2).


The device is packaged in a small 7 x 7mm single-row VQFN-56 package, ideal for 2 or 4-layer PCBs. A low EMI line driver with integrated termination simplifies the PCB design. GPY212 can be operated from a single 3.3V power supply using the integrated DC/DC switching regulator. It is configurable through pin strapping, MDIO interface, or an optional external flash memory.


GPY212 is pin compatible with MaxLinear’s GPY211, GPY215 and GPY115 Ethernet PHYs.
