High-speed Ethernet PHYs for line cards and network infrastructure
Data center, enterprise and carrier networks are moving to higher bandwidth and greater port density, placing more demands on the physical layer. Network platforms must maintain reliable connectivity across increasingly complex system architectures while supporting evolving Ethernet speeds, interfaces and deployment requirements.
The Marvell® Alaska® C series of high-speed PHYs provide the physical-layer connectivity needed to support these transitions across switching and network infrastructure. The product line helps system designers maintain signal quality, interface compatibility and operational flexibility as network bandwidth increases.

Vega
PAM4 clock and data recovery
As high-speed PAM4 interfaces extend across networking systems, signal degradation can limit reliable connectivity between devices. Clock and data recovery can restore signal quality between high-speed interfaces without requiring a full Ethernet PHY feature set.
The Marvell® Vega PAM4 DSP is an octal-port bidirectional clock and data recovery device designed for high-speed PAM4 connectivity. It provides signal conditioning for applications that require high-speed electrical interface extension between system components.
