DUTIES & RESPONSIBILITES:
  • Develop high speed digital signal processing circuit card for 5G access point transceiver system consisting of 10/25/40 Gbps optical interface, fronthaul interface and signal processing in FPGA, DC power conversion circuitry, system clocking and synchronization circuits, and high-speed data converters.
  • Conduct FPGA & CPLD device evaluation to determine best application fit for cost, size, and power consumption.
  • Conduct digital and mixed signal circuit design and schematic capture for all circuitry including QSFP, FPGA, CPLD, ASIC, high speed data converters, power conversion circuits, and clocking circuits.
  • Conduct system architecture analysis, timing analysis, signal integrity simulation, resource estimation, power estimation, DUC/DDC frequency planning, spurious analysis, and mixed signal dynamic range analysis.
  • Lead PCB design ensuring high density FPGA break-out, high speed serial and bus matched length routing and signal integrity, line impedance control, mixed signal noise immunity, and low noise power distribution. 
  • Conduct full PCB assembly verification including initial board bring-up, functional verification, design verification testing, and system integration and testing.
  • Work closely with software and FPGA engineers for board design, initial board bring-up, and feature integration.
 
QUALIFICATIONS:
  • Bachelor's degree in Electrical Engineering required with a minimum of nine (9) years of relevant experience OR Master’s degree in Electrical Engineering with seven (7) years of relevant experience.
