PM8351 Overview
The OctalPHYTM is an octal PHYsical layer transceiver ideal for systems requiring large numbers of point-to-point gigabit links. It provides eight individual serial channels capable of operation at up to 1.25 Gbps, which may be grouped together to form a single 12.5 Gbps bidirectional link. The OctalPHY includes 8B/10B block coding logic (pliant with 802.3z Gigabit Ethernet and FibreChannel requirements) which...
PM8351 Key Features
