About the role

  • 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
  • Insertion loss, return loss, crosstalk, BER, jitter, and statistical eye diagrams
  • Work in either time domain or frequency domain
  • Phase noise analysis as it applies to PLL’s, reference clocks, SerDes TX-RX links
  • Jitter sensitivity measurement and analysis for SerDes IP
  • Organize and manage multiple projects
  • Develop, clearly and effectively document, and track project plans
  • Effectively communicate complex concepts in conversation, presentations and written documents
  • Determine and document applicable requirements for ASIC package and PCB designs, drawing from industry standards, customer requirements, and/or APD Broadcom’s internal performance goals
  • Collaborate with Package and PCB Engineers to fulfill System SI requirements, while balancing objectives (reliability, cost, complexity, etc.)
  • Pre-layout and post-layout modeling and simulation to support package and PCB engineering for signal integrity
  • Document and deliver SI models with supporting documentation to customer and internal engineers
  • Support customer analysis and debug efforts related to our deliverables
  • Understanding of optical/electrical engine concepts and theory of operation, CWDM, OMA, etc..
  • Familiarity with optical channel impairments such as chromatic dispersion (CD) and four-wave mixing (FWM).
  • Power Integrity Concepts: PDN impedance analysis and design, ultra-low impedance measurements, understanding of SMT capacitor performance metrics, use of CPA and/or SI-Wave for PDN simulations.
