These popular TCXO (XO3080/XO3082) and VCXO (XO7080/XO7082) oscillator families have been extended to incorporate frequencies in the range of 10 to 20 MHz. These common family platforms had previously addressed frequency references from > 20 MHz through 125 MHz. The extension of the family to cover these frequencies was achieved through the incorporation of a special AT-cut crystal resonator process. The net result of this is an improvement in close in phase noise performance (-90 dBc/Hz at 10 Hz and -125 dBc/Hz at 100 Hz offsets), as well as the enabling of tighter frequency/temperature performance across all family members over extended operating temperature ranges. The extension to these families is targeted at applications where guaranteed superior stability over extended periods of time (10 to 20 years) and/or over extended operating temperature ranges are absolute application requirements.
