■FEATURES
■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.
