Job description

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 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.
