marvell alaska x 88x2222/m and 88x2242/m integrated dual-port and quad-port multi-speed ethernet transceiver with macsec and electronic dispersion compensation technology product overview the marvell? alaska? x 88x2222/m and 88x2242/m transceiver family is a fully integrated single-chip solution providing end-to- end data transmission over fber-optic networks as well as twinax copper links. it ofers 2- or 4-port devices that perform all physical layer functions associated with 10gbase-r, 2000base-x, 1000base-x and 10gbase-w. in addition, the device supports one port of 10gbase-x4, 40gbase-r4 and 10gbase-x2. the electronic dispersion compensation (edc) engine delivers high-speed bidirectional point-to-point full duplex data transmis - sion at 10.3 gbps per port over a variety of media. the performance of the engine can be reduced to save power in fber-optic applications that do not require edc. the host-side interface supports two or four ports of 10gbase-r, 10gbase-x2, 2000base-x or 1000base-x with two ports of 40gbase-r4 or 10gbase-x4, and one port of 40gbase-r8. any port from the host side can be attached to any port on the line side as long as the speeds match. the device outputs a recovered clock for use in synchronous ethernet applications. the 88x2242m supports the marvell linkcrypt? feature, which is based on the ieee802.1ae macsec protocol. the 88x2242m device also supports the features above those required by the ieee802.1ae macsec protocol. these include the ability to select and flter uncontrolled port trafc; support of packet redirection by addition of a new mac da, sa and ethertype; support of latency minimization for fow control packets; and support for diagnostics, macsec header retention and additional statistics counters. the device also supports the ability to select a secure channel by means other than the sci, fips compliance testing, adaptive rate control to compensate for packet expansion and ethertype matching for the uncontrolled path. sr / lr / dac / lrm C 10g / 40g host interface quad xfi / quad rxaui / dual xaui dual 40gbase-r4 / single 40gbase-r8 quad sfp+ / single qsfp+ macsec (88x2242m only) edc synche jtag con?g. i2c led mdio frame to reg. fig 1. 88x2242/m system block diagram part number description 88x2222 ? 2-port 88X2222M ? 2-port with macsec 88x2242 ? 4-port 88x2242m ? 4-port with macsec
