Product Details

BCM87400A1KRFBG is an Broadcom ethernet PHY.

An Ethernet PHY converts between the digital MAC interface and the physical cable signalling.

This ordering code is specified at 460.

It is used in networking equipment and industrial gateways, where the part has to hold its specification over the life of the equipment.

The closest other ordering code is BCM87800A1KEFBG, which differs in ethernet rate (800GbE against 400GbE).

The data sheet fixes the process technology at 7 nm CMOS.

The lane configuration is 8 system-side lanes to 4 line-side lanes.

The reason to choose it is the fit between the specification and the function it performs on the board.
