Your Team, Your Impact

Marvell’s Architecture team leads the industry in wireline Ethernet communication technologies, delivering solutions for applications ranging from hyperscale data center interconnects to industrial PHYs. Their portfolio spans speeds up to 1.6 Tb/s and supports diverse media types, including optical fibers, high-speed coaxial cables, and shielded/unshielded twisted pair cables. The underlying core technologies that enable these products are state of the art of equalization techniques like Maximum likelihood sequence estimation, timing synchronization, cross talk and echo cancellation techniques, error control coding techniques such as LDPC, product and concatenated codes, combined with architectural and circuit innovations to enable low power high speed implementation of these complex algorithms.

Come join Marvell to work on the DSP and architecture challenges that need to be solved to enable products and technologies that will determine the future direction for the entire industry.
