Features:
Model: Cxx - Series
The Connor-Winfield 2.5x3.2mm 0 00 J 0. 1 8 Temperature Compensated 23 C Crystal Oscillators and Voltage Controlled Temperature Compensated Crystal Oscillators are designed for use in GPS applications requiring tight frequency stability over the -30 to 85C temperature range. Through the use of Analog Temperature Compensation, this device is capable of holding sub 1-ppm stabilities over the wide temperature range. 2.5V or 3.3V Operation Clipped Sinewave Output Logic Ulta-Miniature 2.5x3.2mm SMT Package Frequency Stabilities Available: 0.50ppm, 1.00ppm, 1.50ppm, 2.00ppm Temperature Ranges Available: -30 to 85C Low Power <2mA Low Jitter <1pS RMS Tape and Reel Packaging RoHS Compliant / Lead Free
