Senior Digital Design Engineer

Richardson, TX 75082, USA

Job Type

Visa Sponsorship option (Must be in Richardson TX)

About the Role

About the Position
As a member of our hardware engineering team within the advanced technology group, this role
develops high-speed digital signal processing circuit cards for 5G access point transceiver system
consisting of a 10/25/40 Gbps optical interface, front haul interface and signal processing in FPGA, DC
power conversion circuitry, system clocking and synchronization circuits and high-speed data
converters. You will conduct FPGA & CPLD device evaluation to determine the best application fit for
cost, size and power consumption.

You will make an impact by conducting digital and mixed-signal circuit designs and schematic capture for
all circuitries including QSFP, FPGA, CPLD, ASIC, high-speed data converters, power conversion circuits
and clocking circuits. Perform system architecture analysis, timing analysis, signal integrity simulation,
resource estimation, power estimation, DUC/DDC frequency planning, spurious analysis, and mixed-signal dynamic range analysis. You will be encouraged to 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

Location: Richardson, Texas 75082
