GPY115 is a single port 1Gbit/s Ethernet PHY for the industrial temperature range with PTP (IEEE1588v2), MACsec and Synchronous Ethernet (SyncE) support.


The device supports the 1000BASE-T, 100BASE-TX and 10BASE-Te modes of the IEEE802.3 standard.


GPY115 is connected to the MAC of an SoC or switch with a low pin-count SGMII interface. The SGMII interface supports 10M, 100M and 1Gbit/s rates or IEEE802.3x rate adaptation using pause frames.


GPY115 supports Energy-Efficient Ethernet (EEE) in the 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.


GPY115 supports MACsec (IEEE 802.1AE) point-to-point wire speed encryption and decryption for MAC layer data security, Synchronous Ethernet (SyncE) 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. GPY115 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.


GPY115 is pin compatible with MaxLinear’s GPY211, GPY212 and GPY215 2.5G Ethernet PHYs.
