Marvell samples first 1.6T Ethernet PHY with 100G PAM4 I/Os in 5nm

Marvell has begun sampling the industry's first 1.6T Ethernet PHY with 100G PAM4 electrical input/outputs (I/Os) in 5nm, enabling next-generation 100G serial-based 400G and 800G Ethernet links for high-density switches. The doubling of the signaling rate creates signal integrity challenges, driving the need for retimer devices for high port count switch designs. It's critical that retimer and gearboxes used for these applications are extremely power...
