XC2311 Series ETR1408_005 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. ■FEATURES ■APPLICATIONS ●VCXO modules Supply Voltage Range : 2.6V ~ 3.6V Output Frequency Range : 16MHz ~ 50MHz ●Communication equipment (V2B0 = 16MHz~36MHz, V3B0 = 30MHz~50MHz)* : more than ±110ppm Pull Range (XC2311V2B0xx, VC = 1.65V±1.35V) Output Waveform Symmetry : 50% /±5 % Operating Ambient Temperature : - 40℃ ~ +85℃ Supply Current : 3mA (TYP.)
