Mixed-Signal Clocking and Control RTL Design Engineer

Job Description

As a Mixed-Signal Clocking and Control RTL Design Engineer at Apple, you will be responsible for designing logic used to calibrate and control circuits such as oscillators, delay lines, and phase interpolators.

Requirements

• MS degree in technical discipline with minimum of 10 years of relevant experience
• Excellent knowledge of digital logic gates, clocking, and state elements
• Solid understanding of logic and behavioral simulations, and working knowledge of STA/Lint/CDC/RDC tools
• Good understanding of various phase and frequency detectors, oscillators, delays line, and phase interpolators
• 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

Responsibilities

• Design logic for calibration and control of circuits like oscillators and delay lines
• Analyze control loops for critical parameters such as gain, latency, transients, and jitter
• Collaborate with system architects and design verification teams
• Contribute to post-silicon debug and analysis
