About the role
Broadcom is seeking a SerDes Applications Engineer for the ASIC Product Division (APD) to provide technical customer support from pre-sales through product deployment. The position focuses on SerDes IP performance evaluation, system bring-up, and integration across 100G/200G Ethernet and Gen5/6 PCIe interfaces.
What you'll do
- Validate SerDes performance on test silicon with setups and external channels representing customer applications, collaborating with SI and development teams to resolve performance marginality.
- Test evaluation boards with test silicon, document hardware and software for customer deployment, and support customer evaluation of SerDes performance.
- Develop software and scripts enabling customers to execute automated looping with voltage and temperature margining across multiple configurations and channels.
- Support customer queries regarding SerDes configuration, initialization sequences, APIs, reference clock requirements, STA, electrical interoperability, and power noise specifications.
- Diagnose root causes of link failures, including link downgrade, excessive BER, random and deterministic jitter, inter-symbol interference (ISI), crosstalk, reference clock phase noise, and power supply-induced jitter (PSIJ).
- Author hardware design guides, PCB layout checklists, scope automation scripts, and application notes on fixture de-embedding, S-parameter touchstone file extraction, and equalization tuning.
What you'll need
- MSEE plus 10 years of relevant experience in SerDes design, validation, and system bring-up using 100G/200G Ethernet and Gen5/6 PCIe interfaces.
- Expertise in high-speed serial interface design, equalization techniques, error correction codes used with 200G and 400G serial interfaces, and their signal integrity, crosstalk, and power noise impacts.
- Deep understanding of Ethernet link training, PCIe LTSSM, and familiarity with the respective standards.
- Demonstrated ability to operate, calibrate, and automate high-speed test benches using real-time digital oscilloscopes (50+ GHz), Bit Error Rate Testers (BERT), Vector Network Analyzers (VNA/TDR), and Protocol Analyzers/Exercisers.
- Extensive knowledge of ASIC design flow, including RTL, simulation, synthesis, STA, and DFT.
- Proficiency in scripting using Python or C.
