SiTime is the market leader in silicon MEMS timing offering programmable solutions with a rich feature set that enables customers to differentiate their products with higher performance, smaller size, lower power, and better reliability. Products include precision Super-TCXOs and OCXOs, MHz oscillators and µPower 1-Hz to 26-MHz oscillators – ideal for communications/enterprise, mobile, IoT, automotive, industrial and consumer applications – as well as ruggedized products for aerospace and defense.
ST’s timing heritage goes back to the venerable 555 timer that they still produce. ST also has a wide selection of Real Time Clocks (RTCs) and continue to innovate with their SNAPHAT® devices with special removable/replaceable top that contains a lithium coin-cell battery and a 32-kHz crystal designed to be "snapped on" after the surface mount process. It solves the reflow compatibility of the lithium batteries and provides a solution compatible with all of ST's real-time clocks in surface-mount SOH-28 and SOH-44 packages.
Brandywine Communications offers a complete line of time and frequency systems - from complete timing systems (Master Clocks), to Network (NTP Servers) and IEEE-1588 Precision Time Protocol (PTP) Time Servers, from GPS clocks to time displays. Brandywine offers ruggedized time and frequency standards for military use, high quantities and quick delivery of systems for satellite ground stations, and cost effective systems for infrastructure projects such as airports and rail terminals.
