HIGH STABLE TEMPERATURE-COMPENSATED AND MICROPROCESSOR-BASED QUARTZ OSCILLATOR. CERTIFICATE 30046

The invention can be used for frequency temperature stability improvement at creation of high stable quartz oscillators operating in wide temperature range.

Serial production of small-sized precision supporting quartz oscillator temperature-compensated and microprocessor-based, protected by certificate 30046. It is intended for operation in portable and stationary communication means composition as an efficient source of high stable electric oscillations in operating conditions corresponding with group standards 1.14 State Standard V20.39.304-76 and 1.7.1 State Standard RV20.39.304-98. Depending on oscillator version relative frequency deviation from nominal meaning (10 MHz) can be: 1,010-7, 2,010-7, 3,010-7 for operating temperature range from 40º up to +60º and 50º up to +70º. Long-term frequency instability from all destabilizing factors (total) per year is 3,510-7, 4,010-7, 4,510-7 correspondingly and for 15 years without tuning correspondingly 5,510-7, 6,010-7, 6,510-7. Output signal is a sine with voltage 200 400 mV at loading 51 hm. Due to indicated useful model application quartz oscillators are different by high frequency temperature stability, minor frequency deviation from nominal meaning and simple tuning.
