Lynium has a wide range of expertise and experience in electronic design. Double-data rate (DDR) memory, embedded firmware, PC software, systems-on-a-chip (SOCs), field programmable gate arrays (FPGAs), high-speed digital printed circuit board (PCB) layout, and analog design. A system for testing digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) is one of our main products. For high-resolution and high-speed ADCs, the ATS4000 system is the first of its type to include both AC and DC testing capabilities. We are presently developing the testQube 5220A, a follow-on system.
