PAM4 DSP retimers for active electrical cables
The Alaska® A family of PAM4 DSPs for active electrical cables addresses critical AI data center connectivity trends: the need for higher bandwidth short-reach interconnects to match increasing compute power and the shift from passive to active copper interconnects. The Alaska A family includes the first PAM DSP, the first 100G per lane DSP and the industry’s first 1.6T AEC DSP. Alaska A products are built on Marvell® PAM4 technology deployed in every leading cloud data center.
Alaska A
PAM4 AEC DSP
The Alaska A PAM4 DSP product family is designed for retimer functionality in active electrical cables (AEC). The Alaska A products are optimized for multiple short-reach copper interconnects within data center racks, including AI accelerator-board connections, server to top-of-rack links and switch-to-switch links. With the ability to extend copper reach to > 3 meters at 200G I/O speeds, the Alaska A 1.6T is optimized for the next wave of large language model (LLM) infrastructure.
- Support for both Ethernet and InfiniBand applications (select products)
- Support for >40dB Loss
- 224 Gbps and 112 Gbps PAM4 SerDes
- Enables thinner, longer reach cable
- Significant margin to IEEE (e.g. 802.3ck) and CEI Standards for 100G and 50G PAM4 operation
- Support for IEEE Auto Negotiation and Training protocol
- Comprehensive test and debug capabilities
