Job Description:

2101959 DSP Systems Architect @ marvell.com
This is a high impact opportunity to be part of a team that's the industry leader in wireline Ethernet communication technologies. Marvell's product portfolio addresses applications from Hyperscale data center interconnects to industrial PHYs, reaching speeds of 1.6Tb/s, and covering diverse media types spanning Optical fibers and High speed coaxial cables to shielded and 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.
Responsibilities:

  • Design and simulate DSP architectures, define key capabilities, performance requirements and drive specifications for both analog and digital designers.
  • Create DSP and FEC hardware block specifications appropriate for RTL implementation.
  • Perform research activities in digital signal processing for SerDes and optical channels.
  • Work with designers to ensure circuit architecture can be efficiently implemented.
  • Develop/perform behavioral modeling of mixed-signal circuit designs for transceivers.
  • Provide guidance on test plans for lab characterization once design comes back from fab.
  • Participate in chip lab bring up. Should be comfortable working with lab equipments.
    Requirements:
    • Bachelor's degree in Computer Science, Electrical Engineering or related fields and 10-15 years of related professional experience.
    • Master's degree and/or PhD in Computer Science, Electrical Engineering or related fields with 5-10 years of experience.

      Qualifying Experience:
      • Knowledgeable about the common high-speed serial data protocols NRZ/PAM4 and system standards.
      • Strong experience in communication system modeling in Matlab, C and/or Python.
      • Experience in high-speed DSP, especially FFE/DFE, Clock and Data Recovery (CDR) or FEC (RS, soft decoding, Viterbi algorithm) is a big plus.
      • Experience with ADC-based wireline transceivers and/or coherent DSP architectures is a plus.
      • Experience with high-speed/time interleaved ADC and the associated calibration algorithms is a plus.
      • Experience with either direct-detect/intensity modulated or coherent optical communication is a plus.
      • Team player, willing to take on a variety of projects, good listening skills, self-motivated.
