First 16-port 50GbE PHY transceiver

Marvell announced the launch of the 88X7120 50GbE PHY transceiver, the latest offering in its Alaska C family of high-speed Ethernet physical layer (PHY) transceivers, designed to improve bandwidth and performance in the data center. The new transceiver is purpose-built to address the transition in hyperscale data centers from 25GbE (Gigabit Ethernet) and 100GbE to 50GbE, 200GbE and 400GbE as new applications like artificial intelligence and machine learning continue to drive exponential processing and I/O bandwidth demands. The 88X7120 addresses this I/O speed transition in hyperscale data centers with support of 16 ports of 50GbE, 4 ports of 200GbE and 2 ports of 400GbE, utilizing 50G PAM4 signaling.

Marvell provides a wide variety of products for data center applications and PHYs are a critical element in Marvell’s strategy, as they form the backbone of high-speed data center interconnects. The new transceivers add to the Marvell portfolio of switches and other differentiated products targeted at the data center market, including scaling interconnect speeds to match the I/O throughput requirements in a cost-effective and power-efficient manner.

The transceivers are also the first PHY devices on the market to be fully compliant with new IEEE 802.3cd standards that define PAM4-based 50GbE port types. The port density on the 88X7120 has been specifically optimized to enable QSFP-DD (Quad Small Form Factor Pluggable – Double Density) and OSFP (Octal Small Form Factor Pluggable) port types for 50GbE, 200GbE and 400GbE deployments. The devices also provide gearboxing functionality for translating between PAM4 and NRZ port types to enable a smooth transition to the newer Ethernet speeds, while maintaining support for existing optics and ASIC I/Os. They have a fully symmetric architecture, with long reach SerDes on both system and line side interfaces, to enable system design flexibility and to support both optical and direct-attach copper interconnects. The 88X7120 is sampling to key customers today.
