| 5x7mm Surface Mount High Precision 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 D7 The Connor-Winfield 's D75A 5 12 A 08 .8M 47 Series are 5x7mm Surface Hz Mount Temperature Compensated Crystal Controlled Oscillators (TCXO) with a Tri-State LVCMOS output. Through the use of Analog Temperature Compensation, the D75A - Series are capable of holding sub 1-ppm stabilities over the 0 to 70C temperature range. Features Model D75A TCXO 3.3V Operation LVCMOS Output Logic Frequency Stability: 0.28ppm Temperature Range: 0 to 70C Low Jitter <1pS RMS Tri-State Enable/Disable Function 5x7mm Surface Mount Package Tape and Reel Packaging RoHS Compliant / Lead Free Absolute Maximum Ratings Parameter Storage Temperature Supply Voltage Input Voltage (Vcc) Minimum -55 -0.5 -0.5 Nominal Maximum 85 6.0 Vcc+0.5 Units C Vdc Vdc Note Operating Specifications Parameter Frequencies Available Frequency Calibration @ 25 C Frequency Stability [(Fmax - Fmin)/2.Fo] Holdover Stability (Over 24 Hours ) Supply Voltage Variation (Vcc 5%) Load Coefficient (5%) Static Temperature Hysteresis Total Frequency Tolerance 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 SSB Phase Noise at >100KHz offset (Vcc) (Icc) (Fo) -1.00 -0.28 -0.32 -0.20 -0.20 -4.60 0 3.135 Minimum Nominal 3.3 3 0.5 -80 -110 -135 -150 -150 Maximum 1.00 0.28 0.32 0.20 0.20 0.40 4.60 70 3.465 6 5 1 Units MHz ppm ppm ppm ppm ppm ppm ppm C Vdc mA ps rms ps rms dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz Absolute, 4 5 1 2 3 Note 10.0, 12.8, 19.2, 20.0 Input Characteristics For Enable / Disable Function (Pin 8) Parameter Enable Voltage (High) or open circuit Disable Voltage (Low) Output Tri-stated (Vih) (Vil) Minimum 70%Vcc Nominal Maximum 30%Vcc Units Vdc Vdc Note 6 LVCMOS Output Characteristics Parameter LOAD Voltage Current (High) (Low) (High) (Low) Duty Cycle at 50% of Vcc Rise / Fall Time 10% to 90% Note: Minimum (Voh) (Vol) (Ioh) (Iol) 90%Vcc -4 45 - Nominal 15 50 - Maximum 10%Vcc 4 55 8 Units pF Vdc Vdc mA mA % ns Note 7 Bulletin Page Revision Date Tx236 1 of 2 00 01 Oct 2008 1) 2) 3) 4) 5) 6) 7) Initial calibration @ 25 C. Specifications at time of shipment after 48 hours of operation Frequency stability vs. change in temperature. Inclusive of frequency stability, supply voltage change (1%), load change, aging, for 24 hours Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25C. Inclusive of calibration @ 25 C, frequency vs. change in temperature, change in supply voltage (5%), load change (5%), reflow soldering process and 20 years aging, referenced to Fo. 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). For best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 15pF. Specifications subject to change without notice. All dimensions in inches.
