PRODUCT OVERVIEW
The Marvell® Alaska C 88X5111 is a fully integrated single chip port Ethernet transceiver that performs all physical layer functions required
for 100 Gbps Ethernet Gearbox functionality, and drive 100 Gbps full duplex transmission, over a variety of media including optics,
backplanes and passive copper cables. Manufactured with 28 nanometer lithography, in a 17mmx17mm package footprint, the Marvell
88X5111 enables low-power dissipation, high-density 100GbE card designs. The line interface of the 88X5111 is fully compliant to the IEEE
802.3BJ standard that defines the physical layer specifications for 100 Gbps Ethernet transmission over backplanes and copper cables.
The device supports the Reed Solomon Forward Error Correction (RS-FEC) function required for 100G-CR4, 100G-KR4, and 100G-SR4
operation, as well as auto-negotiation and coefficient-training protocol required by the IEEE 802.3.The device also supports the Multilink
Gearbox (MLG) functionality specified by the OIF MLG 2.0 specifications. The MLG functionality enables aggregation of 10 independent
streams of 10 Gbps Ethernet or two independent streams of 40 Gbs Ethernet onto a 4x25 Gbps stream. The 88X5111 connects to a MAC
or switch on its host interface over a 10x10 Gbps CAUI-10 link. The transmit drive and receiver equalization capabilities of the host
interface meet the requirements of to 10GBase-KR specifications, significantly exceeding CAUI-10 requirements.
On the line side, the device has a 4x25 Gbps interface and supports a variety of media types including single mode and multimode optical
modules, passive and active copper direct attach cables, and copper backplanes. The line interface of the 88X5111 is fully compliant to the
IEEE 802.3BJ standard that defines the physical layer specifications for 100 Gbps operation over backplanes and copper cables. The
device supports the RS- FEC feature, as well as auto-negotiation and coefficient training protocol required by the 802.3BJ. Standard
Internal registers can be accessed via an MDIO/MDC serial management interface which is compliant with the IEEE 802.3 specification
(Clause 45). An MDC frequency of up to 25 MHz supported. The device includes internal PRBS generators and Ethernet packet
generators and loopbacks to assist with test and debug. In addition, non-destructive eye monitoring is supported on all high speed I/Os.
The 88X5111 is housed in a 17 mm x 17mm 256 pin FCBGA package, and supports an operating temperature range from 0 to 105°C.
