Hardware Systems Signal Integrity Engineer iPhone

The people here at Apple dont just create products they create the kind of wonder thats revolutionized entire industries. Its the diversity of those people and their ideas that inspires the innovation that runs through everything we do from amazing technology to industry-leading environmental effortsnnThe iPhone System Technologies organization is seeking a Signal Integrity Engineer for the hardware development this highly collaborative role you will interface with various technology and module teams (such as camera display sensors etc.) to influence their integration at the system level with emphasis on design and debug of high-speed and low-speed team is collaborative creative and passionate about what we do and the products we make. We want to hear from you!

We are seeking a candidate with a strong background in Signal Integrity including Lab and Simulation experience. Knowledge of electromagnetics transmission line theory extracting channel models and simulating EMI/Crosstalk are expected. Channel elements include rigid PCBs flexible printed circuit boards connectors and other components in a mobile system.

Participating in schematic reviews to inform selection and placement of various system level channel components including RLC filters DC-blocking capacitors board to board connectors etc. nnSimulating loss crosstalk and coupling concerns to guide layout u0026 system design using 3D/2.5D/2D EM modeling tools. nnLeading layout reviews and making data-driven recommendations to achieve robust SI performance on various signals running at low and high speeds. nnPerforming design feasibility study design testing and verification and system bring design guideline and supporting to system architecture design board layout product bring up debug validation and factory builds. nnPerforming time-domain and statistical simulations to qualify signal integrity and optimizing driving strengths and equalization to ensure adequate voltage and timing margins over high lab measurements such as VNA characterization Eye Diagrams BERTs and Compliance Testing. nnWorking with multi-functional teams to define design requirements for improved EM performance and system coexistence by developing and improving design methodologies to achieve minimal EMI.
