System Signal/Power Integrity Engineer

Responsibilities:

• Support high data rate SerDes applications – up to 400G 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
