Symmetricom, Inc., precision time and frequency technology company, today announced the company will sell GPS disciplined oscillator (GPSDO) modules and high-frequency source modules from Jackson Labs Technologies, Inc., a designer and manufacturer of cutting-edge precision time and frequency products. GPSDOs provide time and frequency reference signals that have the same long-term accuracy as the GPS signal itself, and also provide a “holdover” capability to maintain system synchronization when GPS reception outages occur, Symmetricom said, adding that this new set of solutions provides Symmetricom’s customers with a broader range of product options, supporting a variety of price and performance levels.
