RS-GGOxx-T2P are reference oscillators with the same form factor as standard OCXO's (1"x1") but that's all it has in common with them. Instead of drawing a lot of current to heat the crystal it contains a temperature compensated crystal oscillator with 2.5ppm stability which can be locked to a 1 Pulse Per Second (1PPS) signal from a GPS receiver. A combination of novel circuits, special firmware algorithms and patented Nano-Technology enable a low current miniature unit with an attractive price. This type is usally called a GPS disciplined oscillator.
Within less than 2 minutes after GPS lock has been achieved the RS-GGOxx-T has already reached its specified accuracy of better then 5x10E-9, a value where you have to wait a long time before it's achieved by an OCXO.
A test board with (RS-TBGGO) and without GPGS receiver (RS-TBGGO-NG) is available

RS-GGO10-T is discontinued and replaced by RS-T2P
