3 Description
The FPC402 quad port controller serves as a low-
speed signal aggregator for common port types such
as SFP, QSFP, Mini-SAS HD, and others. The
FPC402 aggregates all low-speed control and I2C
signals across four ports and presents a single easy-
to-use management interface to the host (I2C or SPI).
Multiple FPC402s can be used in high-port-count
applications with one common control interface to the
host. The FPC402 is designed to allow placement on
the bottom side of the PCB, underneath the press fit
connector, to simplify routing. This localized control of
the low-speed signals in the ports cuts system BOM
costs by enabling the use of smaller IO count control
devices (FPGAs, CPLDs, and MCUs) and by
reducing routing layer congestion.
