Mixed-Signal Clocking and Control RTL Design Engineer

At Apple, we are dedicated to designing products that enrich the lives of our users. Are you passionate about tackling challenges that have yet to be resolved? Do you thrive in innovative environments? We have a technically demanding Mixed-Signal Clocking and Control RTL Design position on our team. As a valued member of this group, you will have the opportunity to contribute to the development of groundbreaking products that will captivate and empower millions of customers worldwide.

In this role, you will be responsible for designing logic used to calibrate and control circuits such as oscillators, delay lines and phase interpolators. The logic design will involve working with multiple clocks, complex clock domain crossings, signal processing and control systems. You will need to analyze control loops for critical parameters such as gain, latency, transients and jitter. You will work closely with static timing experts for timing closure and front-end quality tools such as Lint/CDC/RDC. You will work with system architects to determine implementation of new designs, and with design verification teams to craft/debug tests. You will also contribute to post-silicon debug and analysis of these designs.

• MS degree in technical discipline with minimum of 3 years of relevant experience.

• Excellent knowledge of digital logic gates, clocking and state elements
• Excellent knowledge of writing synthesizable code in SystemVerilog
• Solid understanding of logic and behavioral simulations, and working knowledge of STA/Lint/CDC/RDC tools
• Solid understanding of clocking fundamentals such as jitter, phase and frequency modulation
• Good understanding of various phase and frequency detectors, oscillators, delays line and phase interpolators
• Prior experience working on clocking circuits such as PLLs/DLLs/CDRs
• Familiarity with DACs and oversampling modulators
• Familiarity with SERDES clocking and Equalization, line coding schemes and multi-level signaling
• Familiarity with the basics of digital signal processing and closed loop control
