Sinc Squared was founded as a side business in 2012 located in Portland, Oregon by full-time professional signal integrity engineers. The first product was a USB-3 to SMA breakout board that was inspired by continual need for such a device at our full-time employer. Our purpose is to provide high-quality multi-gigabit test fixtures and reference designs that help accelerate the adoption of broad-band digital communications protocols such as USB-3.0, SATA, Ethernet, Fibre Channel, HDMI, DisplayPort, and PCI Express. Products are designed by seasoned signal integrity engineers with 20+ years of industry and standards committee experience. Particular attention is focused on meeting or exceeding all physical-layer standards, including impedance-matched transmission lines, deterministic jitter budgets, and ease of use. All products are designed and built in the USA.
