GPY211C0VC
Overview
The GPY211C0VC is a low-power 2.5 Gigabit Ethernet PHY designed for high-speed connectivity in space-constrained applications. It supports multi-rate operation including 10/100/1000BASE-T and 2500BASE-T, interfacing with a MAC via SGMII or USXGMII. This 56-pin VQFN device integrates a DC/DC switching regulator and features precise IEEE 1588v2 time stamping for synchronized networking.
Why Choose This Part
The IC features an integrated DC/DC converter that allows operation from a single supply, reducing external component count. It offers exceptional power efficiency with an ultra-low power mode consuming only 10mW when the cable is unplugged. Additionally, the voltage-mode line driver ensures low EMI while integrated termination resistors simplify PCB layout.
Applications
Key Specifications
Getting Started
Designers should prioritize PCB thermal management using the 56-VFQFN exposed pad and ensure the MDIO interface is configured for the desired message frame type (Clause 22 or 45). The SPI interface can be used for secure firmware upgrades to the local flash memory. Evaluate performance using MaxLinear's reference designs for 2.5GBASE-T applications to ensure signal integrity at higher baud rates.
