Pad Size 80 x 80 Жm Chip Thickness 200 + 10 Жm ˙APPLICATIONS ˔VCXO modules ˔Communication equipment ˙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 cons tant-voltage circuit built-in, t he 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 Supply Voltage Range : 2.6V ~ 3.6V Output Frequency Range : 16MHz ~ 50MHz (V2B0 = 16MHz~36MHz, V3B0 = 30MHz~50MHz)* Pull Range : more than ʶ110ppm (XC2311V2B0xx, V C = 1.65Vʶ1.35V) Output Waveform Symmetry : 50% /ʶ5 % Operating Ambient Temperature : - 40 ˆ ~ +85 ˆ 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 : Chip size 1000 x 750 Жm * Please refer to the Electrical Characteristics for versions’ details. ˙CHIP PAD LAYOUT ˙PAD COORDINATE ETR1408_005 Unit (Жm)
