◆Power Supply Voltage Range: 2.6V~ 3.6V ■APPLICATIONS ◆Operating Frequency Range : 16MHz~50MHz ●VCXO modules (varies with version) ●Communication equipment ◆Supply Current : 3mA (TYP.) (when VDD is 3.6V, 27MHz and output is enable) ◆CMOS Output ◆Ultra Small Packages : SOT-26, USP-6C SOP-8 ◆Chip Form ■GENERAL DESCRIPTION ■FEATURES 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.
