Marvell Alaska X 88X2340P
Quad 10G Ethernet Transceiver with MACsec and IEEE 1588v2 PTP support
MARVELL ALASKA X 88X2340P OVERVIEW
The Marvell® Alaska® X88X2340P is a fully integrated, quad-port 10G, transceiver that
performs all physical layer functions required to drive 10G Ethernet over a variety of media
including SR/LR optics and passive Direct Attach Cables.
The 88X2340P supports encryption applications through Marvell’s LinkCrypt feature that is
based on the IEEE 802.1AE MACsec protocol. The supported features include the ability to
select and filter traffic, packet redirection, and latency minimization for flow control packets.
The 88X2340P also supports IEEE 1588 v2 1–step and 2-step time-stamping functionality for
precision timing applications. The device contains a PTP block, designed for parsing and
modification of PTP frames as they pass through the device to support 1-step time
stamping. The integrated PTP and MACsec functionality allows for parsing of MACsec
encrypted PTP packets to support encrypted PTP timing propagation.
Manufactured in 28 nanometer (nm) lithography, in a 23mmx23mm package footprint, the
Marvell 88X2340P enables low-power dissipation, high-density 10G Ethernet designs that
support features such as encryption and precision timing.
