About The Position

Requirements

• PCB design fundamentals (single ended and differential signals)
• Signal loss
• Impedance control
• Crosstalk (near end and far end)
• Experienced with single-ended and differential signaling up to 50Gbps
• Experienced working with component models (touchstone files) and cascading models to generate complete system models for simulation
• Simulation of digital interfaces (FPGA to DRAM, SERDES interfaces)
• Simulation of analog paths through a combination of PCB, connector, and cable (signal driver to DUT)
• Proficient with 2D and 3D simulation tools (examples include ADS, ANSYS HFSS, Sigrity)
• Electrical length calculations for signal matching
• Familiar with looking at signals in both frequency (S-parameter) and time domain and understand how to interpret results when it comes to suitability for a particular application.
• Very familiar with generating and interpreting data-eye diagrams up to 50Gbps: NRZ and PAM4
• Proficient with Allegro or similar layout tool and schematics
• PCB Stack up design and familiar with fabrication limitations and cost trade-offs
• High Frequency board material experience
• Significant experience with measuring signal performance in the lab: TDR measurements and VNA measurements
• Able to develop test fixtures for making measurements (both custom design test boards as well as making “ad hoc” probing solutions to troubleshoot existing PCBs)
• Expert in cost vs performance tradeoffs when designing signal paths as cost is key design constraint
• Experience with flex circuit design for high speed signaling
• 12+ years experience with High Speed Signal Delivery Design and Evaluation. This includes both signal integrity within a PCB and off the board (board to board connectors, ribbon cables, coaxial cable, etc.).
• Bachelor’s degree in Electrical Engineering, Master’s is preferred
