VCXOs with Frequency Multiplier

IDT VCXO devices provide variable-frequency clock outputs that serve as the variable-frequency oscillator (VFO) element in a discrete PLL circuit. Using a pullable fundamental-mode crystal in the range of 12 MHz to 40 MHz, the VCXO stage provides a pullable-frequency reference to the frequency multiplier. The frequency multiplier provides high frequency outputs up to 800 MHz. These can be used in many applications to replace expensive single frequency VCSO products.
