Abstract

Internally heated quartz resonators (IHQRs) offer opportunities for design of high-stability quartz oscillators with low power consumption, fast warm-up, small size, and resistance to severe operating conditions. The development of IHQRs and oscillators to meet the requirements of new electronic systems is described. The performance of IHQRs and quartz oscillators is significantly improved: long-term frequency stability up to 2×10^m-10 per day and 3×10^-8 per year; power consumption to 150 mW at -60°C and 65 mW at +25°C; and IHQR overall dimensions to 10 cm ³. The transition to `binary code´ frequencies of 16.384 MHz and 6.4 MHz is made, and the transfer function of the voltage-compensated crystal oscillator (VCXO) on IHQR is linearized
