The FPC401 quad port controller serves as a low-speed signal aggregator for common port types such as SFP+, QSFP+, and SAS. The FPC401 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 FPC401s can be used in high-port-count applications with one common control interface to the host. The FPC401 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 ports’ low-speed signals cuts system BOM cost by enabling the use of smaller IO count control devices (FPGAs, CPLDs, MCUs) and by reducing routing layer congestion.
