| Sub-Miniature Precision 3.2x2.5mm Clipped Sinewave TCXO In Stock at Digi-Key Description 2111 Comprehensive Drive Aurora, Illinois 60505 Phone: 630-851-4722 Fax: 630-851-5040 www.conwin.com US Headquarters 630-851-4722: European Headquarters: +353-61-472221 Features 8J .2 G 19 D 3 2 The Connor-Winfield's D32G series are 3.2x2.5mm Surface Mount Temperature Compensated Crystal Oscillator (TCXO). Through the use of Analog Temperature Compensation, the D32G series are capable of holding sub 1-ppm stabilities over the -30 to 85C temperature range. Model D32G TCXO 3.3Vdc Operation Clipped Sinewave Output Logic Frequency Stability: 0.50ppm Temperature Range: -30 to 85C Low Jitter <1pS RMS 3.2x2.5mm Surface Mount Package Tape and Reel Packaging RoHS Compliant / Lead Free Specification Absolute Maximum Ratings Parameter Storage Temperature Supply Voltage Input Voltage Operating Specifications Parameter Frequencies Available Frequency Calibration @ 25C Frequency Stability [(Fmax - Fmin)/2.Fo] Supply Voltage Variation (Vcc 5%) Load Coefficient (5%) Static Temperature Hysteresis Frequency shift after reflow soldering Aging Temperature Range Supply Voltage Supply Current Period Jitter Phase Jitter (BW=12kHz to 20MHz) SSB Phase Noise at 10Hz offset SSB Phase Noise at 100Hz offset SSB Phase Noise at 1KHz offset SSB Phase Noise at 10KHz offset Clipped Sinewave Output Characteristics Parameter Output Voltage Output Load Resistance Output Load Capacitance Minimum 1.00 Nominal 10K 10 Maximum Units V pk-pk Ohms pF 6 Note 5 (Vcc) (Icc) (Fo) -1.00 -0.50 -0.025 -0.025 -1.00 -1.0 -30 3.135 Minimum Nominal 3.3 3 0.5 -80 -110 -130 -145 Maximum 1.00 0.50 0.025 0.025 0.4 1.00 1.0 85 3.465 2 5 1 Units MHz ppm ppm ppm ppm ppm ppm ppm/year C Vdc mA ps rms ps rms dBc/Hz dBc/Hz dBc/Hz dBc/Hz Absolute 3 4 1 2 Note 16.368, 19.2, 26.0 (Vcc) Minimum -55 -0.5 -0.5 Nominal Maximum 85 6.0 Vcc+0.5 Units C Vdc Vdc Note Bulletin Page Revision Date Tx240 1 of 2 03 17 Dec 2009 Note: 1) Initial calibration @ 25C. Specifications at time of shipment after 48 hours of operation 2) Frequency stability vs. change in temperature. 3) Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25C. 4) Within two hours after reflow. 5) Output is DC coupled. 6) For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 10pF. Specifications subject to change without notice. All dimensions in inches.
