The Opportunity

The Marvell Processor Business Unit post silicon validation group designs and develops test platforms for validating multi-core Arm-based Network processors used in many communication infrastructure applications such as 5G base stations and cloud computing platforms. The electrical characterization team is a post silicon validation sub-group focused on the debug and characterization of SerDes and DDR interfaces on the processor. The SerDes interface runs at speeds up to 56Gbps PAM4 and are used for several protocols including Ethernet and PCIe. The DDR interface runs at DDR5 speeds up to 5600MT/s. Characterization engineers are responsible for developing test platforms used and automated test suites to characterize the analog interfaces over process voltage and temperature (PVT) extremes to determine if the silicon is viable for volume production.

Job Responsibilities:

As a member of a dynamic development team, the you will be responsible for contributing to the analysis, and debug of high speed SerDes IO. In this role you will participate in debugging the SerDes analog interface to improve SerDes/PLL performance and resolve issues over PVT. Participation in these tasks will allow you to gain insight into the operation of state-of-the-art SerDes analog circuits including PLL’s, Clock and Data Recovery circuits as well as Transmit FFE, Receiver CTLE and DFE equalization circuits.

In this role you will:

  • Contribute to debugging SerDes/PLL analog circuits for performance optimization or to root cause failures.
  • Electrical characterization/compliance testing of PCIe and Ethernet SerDes interfaces.
  • Contribute to the design of High-Speed PCB's used for electrical characterization/compliance testing.
  • Hardware support for the functional validation teams on lower speed IO including USB, EMMC & SPI.
  • Low-level protocol debug of PCIe and Ethernet interfaces including initialization and link training.


Bachelor’s degree in Computer Science, Electrical Engineering or related fields and 5-10 years of related professional experience Or Master’s degree and/or PhD in Computer Science, Electrical Engineering or related fields with 3-5 years of experience.
