System Signal/Power Integrity Engineer

Responsibilities

• Support high data rate SerDes applications - up to 112Gbps NRZ and 224G PAM4 systems

• System level Signal and Power Integrity design trade-offs and debug.

• Collaborate with package, PCB, and silicon designers to complete measurement-simulation correlation projects.

• Develop models with electromagnetic field solvers: primarily with Ansys HFSS and electronic suite.

• Ability to understand laminate design and fabrication techniques and limitations for both package and PCB designs.

• Evaluate system, PCB and package material and connector solutions for future designs.

• Simulate schematic models and environments within Keysight ADS.

• Ensure and know trade-offs for the accuracy of models (3D/2.5D/2D) used for design simulations.

• Perform and develop VNA/TDR (50GHz+) measurement techniques and correlate with models and simulations.

• Provide feedback and learnings from measurement-simulation correlation investigations to improve best practices for modeling and simulations.

• Capture high fidelity lab measurements to be used for correlation and debug purposes

• Experience with sampling and real-time oscilloscopes, spectrum analyzers, and optical oscilloscopes.

• Understand and apply:

  • High speed data communications

  • Transmission-line and electromagnetic-field theory

  • Numerical analysis

  • VNA/TDR measurements

  • Bit-by-bit and Statistical simulators for serial data (SerDes) links
