■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.
