SerDes Circuit Design Engineer

About This Role

Join Apple's high-speed SerDes team as an Analog Mixed-Signal designer to build next-generation wireline transceivers. This role involves creating and executing state-of-the-art IPs for Apple’s system-on-chip products.

Responsibilities

• Work on the development of high-performance and high-speed AMS circuits used in SerDes PHY
• Evaluate different circuit topologies for specific product requirements (e.g., Rx, CDR, Tx, bias generator, high-speed clock generation and low-jitter distribution, high-speed analog signal chain, mixed-signal calibration and algorithms) with best in class power, performance, and area (PPA)
• Work with cross-functional teams (e.g., architecture, SIPI, packaging, board design, DFT, ESD) to create block-level specifications
• Execute on transistor-level implementation and behavioral modeling
• Drive mask design to implement layout view of designs
• Closely work with SOC teams to deliver IP views and ensure they meet quality standards
• Interact with peers and management to communicate progress and discuss new ideas

Nice to Have

• Deep understanding of analog mixed-signal design with experience in high-speed serial links
• Understanding and experience of designing analog mixed signal circuit blocks including Bandgap, biasing circuits, LDO regulators, amplifiers, comparators, switched-cap circuits, ADCs, DACs, Oscillators, Filters
• Understanding of analog mixed-signal concepts like mismatch mitigation, linearity, stability, low-power and low-noise techniques
• Good grasp and understanding of digitally assisted analog design concepts (e.g. background calibrations, LMS based adaptive loops)
• Experience with high-speed digital circuits (e.g., serializer, deserializer, counters, dividers, etc.) with solid understanding of digital design concepts
• Knowledge of Tx/Rx equalization techniques and circuits (e.g. CTLE, DFE, de-emphasis) for 64+ Gbps NRZ and PAM applications
• Knowledge of CDR architectures and implementations
• Knowledge of lab equipment and testing
• Experience in Analog Mixed Signal circuit modeling and performance evaluation (e.g. SystemVerilog, Matlab, Python, VerilogAMS)
• Hands-on experience in advanced CMOS technologies, design with FinFet technology
• Hands-on experience with AMS IC development from definition to high-volume production including layout supervision, bench evaluation, correlation, and characterization
• Concepts of timing closure and related industry tools (e.g., Nanotime, Primetime)
• Experience in lab testing of high-speed serial I/O, debug and data analysis techniques
• Knowledge of common high-speed SerDes protocols (e.g., PCIe, USB, DP, MPHY)
• Skills in scripting and automation to enhance efficiency
