VCXO ICs with Built-in Variable Capacitor
■GENERAL DESCRIPTION
The XC2311 Series is VCXO (Voltage Controlled Crystal Oscillator) ICs with built-in variable capacitor diode.
With the originally developed variable capacitor diode and a constant-voltage circuit built-in, the series achieves the wide
variable frequency range, frequency stability to supply voltage and low power consumption.
By combining with the AT-cut crystal oscillator, the ultra small and highly accurate Frequency Voltage Controlled Crystal
Oscillator of 16 to 50MHz can be formed.
The small SOT-26, USP-6C, and SOP-8 packages make high density mounting possible.
