Marvell introduced the industry’s first 1.6T Ethernet PHY solution using a 5nm process, supporting 100G PAM4 input/output. Marvell said that data centers need to further increase bandwidth to meet the demand for massive data growth. This also promotes the transition of the Ethernet backbone network to 1.6T, and 100G serial I/O can play a key role in the cloud service infrastructure to brings scalability to workloads such as artificial intelligence, machine learning, and the cloud.
Alan Weckel, founder and technical analyst of 650 Group, said that 100G serial electrical signals are very important because they will be the foundation for the next generation of high-speed networks. As I/O rates increase, signal integrity often faces challenges. Marvell 1.6T Ethernet PHY solution (Alaska 88X93160) supports next-generation 100G serial 400G and 800G Ethernet connections for high-density switches. “It’s critical that retimer and gearboxes used for these applications are extremely power efficient. Implemented in the latest 5nm node, the Marvell 800GbE PHY provides a 40% savings in I/O power compared to existing 50G PAM4 based I/Os.
This is also the industry’s first PHY device that fully complies with the IEEE 802.3ck 100G serial I/O standard and the Ethernet Technology Alliance 800GbE specification.
With the introduction of a new generation of products, Marvell will maintain a leading position in the high-speed retimer and speed regulation field, provides different product combinations from 10GbE to 800GbE, and supports MACsec encryption/IEEE1588 PTP timestamp complying with Class C standards. At present, Marvell
has begun to provide relevant samples of 1.6T Ethernet PHY solutions to some customers.
