Cynthia Downs Email & Phone Number

Self-motivated and disciplined designer with 15+ years of experience in PCB design, well-versed in electrical constraints for high speed signals, phase tuning, and length matching critical interfaces as well as power distribution. Designed very complex Low Level Analog, Digital, Rigid-Flex, RF amplifiers and RF antenna layouts for both commercial and military applications. Design per IPC and MIL standards, DFM (Design for Manufacturing) and DFT (Design for Test). Designs include complex-dense double sided SMT with high layer count, high component count and high pin count FPBGA's. Thru hole and mixed technologies with challenging requirements including high speed rules, controlling clock skew, trace impedance, length matching, phase matching, loop area and grounding to achieve goals in signal integrity and radiated emissions performance. Layouts include PCI, PCI-Express, DDR2, DDR3, DDR4, HDMI, JTAG, SPI, I2C, I2S, SGMII, USB, UART, WLAN, MSM, PMIC, PCM3060/PCM3070 Codec, multi-gigabit tranceivers, Gigabit Ethernet, highspeed SerdeS, PHY’s, Rambus and Xilinx Artix-7 chip sets. Responsible for creating library parts, shapes, schematic symbols and schematics. Contributor in departmental and cross functional meetings, technology activities and directional discussions. Collaborate with Hardware and Mechanical engineers to provide board stackup to fab vendor. Proficient with: Mentor Graphics BS/RE, Expedition, Xpedition VX.2.3, Valor-NPI, CAM350 and BluePrint-PCB.Other tools: Cadence Allegro, OrCAD Capture and Mentor Graphics Schematic Capture.

Listed skills include Pcb Design, Schematic Capture, Design For Manufacturing, Analog, and 14 others.
