3 Description

The FPC202 dual port controller serves as a low-

speed signal aggregator for common port types such

as SFP, QSFP, Mini-SAS HD, and others. The

FPC202 aggregates all low-speed control and I2C

signals across two ports and presents a single easy-

to-use management interface to the host (I2C or SPI).

Multiple FPC202s can be used in high-port-count

applications with one common control interface to the

host.
