| 3.3V Surface Mount 5x7mm Stratum 3 HCMOS TCXO T501 Features: TCXO 2111 Comprehensive Drive Aurora, Illinois 60505 Phone: 630- 851- 4722 Fax: 630- 851- 5040 www.conwin.com The Connor-Winfield T501 is a 5x7mm Surface Mount, Temperature Compensated Crystal Oscillator (TCXO). Operating at 3.3Vdc, the T501 will maintain 4.6ppm frequency tolerance over 20 years. The T501 is offered for applications where small size and Stratum 3 performance are required. 3.3V Operation Low Jitter <1 pS RMS Overall Frequency Tolerance: 4.6ppm over 20 Years Hold Over Stability: 0.28ppm Temperature Range: 0 to 70C Tri-State Enable / Disable Surface Mount Package Tape and Reel Packaging Maximum 125 7.0 7.0 Absolute Maximum Ratings Parameter Storage Temperature Supply Voltage (Vcc) Enable / Disable Voltage Minimum -55 -0.5 -0.5 Nominal - Units C Vdc Vdc Notes Operating Specifications Parameter Frequency Range (Fo) Supply Voltage (Vcc) Supply Current (Icc) Jitter: (BW=10 Hz to 20 MHz) (BW=12 kHz to 20 MHz) SSB Phase Noise at: 10 Hz offset 100 Hz offset 1 kHz offset 10 kHz offset Minimum 12.8 3.135 - Nominal 3.3 -85 -110 -125 -135 Maximum 20.0 3.465 6 5 1 - Units MHz Vdc mA ps RMS Notes dBc/Hz Hold Over Stability Parameter Hold Over Stability ([Fmax-Fmin]/2*Fo) Temperature Range Total Hold Over Stability Minimum -0.28 0 -0.32 Nominal - Maximum +0.28 70 +0.32 Units ppm C ppm Notes 1 Free Run Accuracy Parameter Total Frequency Tolerance Temperature Range Minimum -4.6 0 Nominal - Maximum +4.6 70 Units ppm C Notes 2 Input Characteristics Parameter Enable Voltage (High) or open circuit (Vih) Disable Voltage (Low) Output Tri-stated ((Vil) Minimum 0.6 - Nominal - Maximum 0.2 Units Vdc Vdc Notes 3 HCMOS Output Characteristics Parameter US Headquarters: 630-851-4722 European Headquarters: +353-61-472221 Bulletin Page Revision Date Minimum 0.9 *Vcc 45 - Nominal 50 - Maximum 15 0.1 *Vcc 55 9 Units pf Vdc % nS Notes Load Voltage: High (Voh) Low (Vol) Duty Cycle at 50% of Vcc Rise / Fall Time 10% to 90% Tx100 1 of 2 02 05 Nov 2003 Notes: 1. Inclusive of Hold Over stability, supply voltage change (5%), aging, 24 hours 2. Inclusive of calibration @ 25C frequency vs. change in temperature, change in supply voltage (5%), load change (5%), reflow soldering process and 20 years aging. 3. Leave Pad 8 unconnected if enable / disable function is not required. When tri-stated, the output stage is disabled but the oscillator and compensation circuit are still active (current consumption 1 mA).
