Alaska C - Ethernet Transceiver
88X93160
Dual 800G, Quad 400G, Octal 200G, 16 port 100G Ethernet Transceiver with Passive Direct Attach Cable and Backplane Drive capabilities
Overview
The Marvell® Alaska® C 88X93160 is a fully integrated single chip Ethernet transceiver with Long Reach 100G PAM4 I/Os to drive passive direct attach cables (DAC) and backplanes. The device supports two ports of 800 GbE, four ports of 400 GbE, 8 ports of 200 GbE or 16 ports of 100GbE. The device is targeted to next generation high density networking solutions based on 100G serial electrical signaling. The device also supports a variety of gearboxing modes to translate between 50G PAM4 and 100G PAM4 modes for 400GbE, 200GbE and 100 GbE, with the necessary FEC termination and regeneration capabilities. The Long Reach Multi mode (112G PAM4, 56G PAM4 and 25G/10G NRZ) SerDes on the X93160 is fully compliant to the IEEE 802.3ck, 802.cd and 802.bj electrical specifications for transmission over passive direct attach (DAC) cables and copper backplanes.
The device supports FEC generation and termination capabilities for all FEC types defined by IEEE 802.3ck, 802.3cd, 802.3by, 802.3bj, 802.3ba, 802.3ap and the 25 Gigabit Ethernet Consortium for 800GbE, 400GbE, 200 GbE, 100 GbE, 50 GbE, 40 GbE, 25 GbE, and 10 GbE operation. The supported FEC types include Clause-134 RS (544, 514), Clause-91 and Clause108 RS (528, 514) RS-FEC, and FC (2212, 2080) FEC. The device supports Auto-Negotiation and coefficient training protocol required by the IEEE 802.3 to support operation over KR backplanes and CR passive DAC cables. The device has a fully symmetric architecture with FEC generation and termination functionality, and Auto-Negotiation and training capabilities on both host and line interfaces to provide complete system design flexibility. The device also includes a full 8x8 SerDes crossbar to support port multiplexing applications. The 88X93160 is packaged in a 27mmx27mm FCBGA package with 0.9mm ball pitch.
