SG8101-Slide7

The SG-8101 is able to provide higher stability with integrated temperature compensation. The plot on the upper left hand corner shows a typical output curve of an AT-cut crystal, frequency versus temperature. With a typical SPXO oscillator, what users put in is what they get out. With the integrated temperature sensor and temperature compensation circuit of SG-8101, the curve can be smoothed out as shown in lower left hand corner. The final block diagram for an SG-8101 with the temperature sensor & compensation circuit integrated is shown. Now the stability can be as low as ±15ppm and it can operate up to 105ºC.
