Saelig Company, Inc has introduced the RSGGO10T3G and RSGGO10T3P reference oscillators with the same form factor as standard ovenized crystal oscillators (OCXO - 1”x1”) but instead of a current-hungry oven they contain a temperature-compensated crystal oscillator with 100ppb stability locked to a 1 pulse per second (1pps) signal from an external (T3P) or integrated (T3G) GPS receiver. A combination of novel circuits, special firmware algorithms, conformal-coating, and patented nanotechnology provide a low-current miniature unit with very high performance at an attractive price.
