| VCXO Page 1 of 3 REV D. VS4 SERIES: VCXO OSCILLATOR, HCMOS, +3.3 VDC, 7x5mm Package DESCRIPTION: A crystal controlled, high frequency, highly stable, voltage controlled oscillator, adhering to HCMOS Standards. The output can be Tri-stated to facilitate testing or combined multiple clocks. The device is contained in a sub-miniature, very low profile, leadless ceramic SMD package with 6 gold contact pads. This miniature oscillator is ideal for today's automated assembly environments. APPLICATIONS AND FEATURES: " Common Frequencies: 16.384 MHz; 19.44 MHz; 27 MHz; 38.88 MHz; 51.84 MHz; 77.76 MHz " +3.3 VDC HCMOS " Frequency Range from 1 to 125.000 MHz " Miniature Ceramic SMD Package Available on Tape and Reel " Lead Free and ROHS Compliant ELECTRICAL PARAMETERS: PARAMETER Nominal Frequency Supply Voltage Supply Current MAX Output Logic Type Load Output Voltage Levels Duty Cycle Rise / Fall Time Jitter Overall Frequency Stability Control Voltage Range Settability Absolute Pull Range Input Impedance Modulation Bandwidth Pin 2 Output Enabled Output Disabled Voh Vol DC tr / tf J f/fc VC Vfo APR Zin BW En Dis Vcc(abs) -3 dB High Voltage or No Connect Ground Non-Destructive Minimum guaranteed freq. pull over f/fc Measured at 50% of Vcc Measured at 20/80% and 80/20% Vcc Levels RMS, Fj = 12 kHz...20 MHz Peak-to-peak Op.
