Single Port 2.5G Ethernet PHY
Product Flyer


The GPY215 is a single-port 2.5GbE PHY for industrial applications that includes MACsec and SynE. It is also well suited for routers, switches, and home gateways. It provides interoperability for NBaseT and the new IEEE 802.3bz standard. It is also optimized to work with 2.5GbE PHY for PCs.
The device temperature is monitored by an internal thermal sensor that provides thermal information for system warnings or initiates speed reduction to prevent system overheating. It supports a timing synchronization according to the IEEE 1588v2 and SyncE standard required for Industrial, transportation, and mobile networking.
The GPY215 also supports MACsec point-to-point wire speed date security and is configurable through pin strapping, MDIO interface, or external flash.
The rate adaptation function is to help MAC which cannot support lower speed. The fix MAC rate between PHY and MAC and TP interface run at different speed.
The GPY215 supports energy-efficient Ethernet to reduce power consumption depending on traffic. Additionally, the power can be saved at the system level by using the wake-on-LAN (WoL) functionality, the ultra-low power mode, and the no link states.
The GPY215 is packaged in a small 7 x 7mm single-row VQFN-56, ideal for 2 or 4-layer PCBs. The low EMI line driver with integrated termination simplifies the PCB design. The SGMII+ interface supports 10/100/1000/2500 speeds. The device can be operated from a single 3.3V power supply using the integrated DC/DC switching regulator.
