The HFF crystal is a high-Q quartz device that enables the circuit to achieve low phase jitter performance over a wide operating temperature range. The oscillator is housed in an industry standard hermetically sealed leadless surface mount package and is available on tape and reel. 10188_VECTRON 05/21/03 3:14 PM Page 2 VC-700 Voltage Controlled Crystal Oscillator Electrical Performance Parameter Frequency Supply Voltage Supply Current Output Logic Levels Output Logic High Output Logic low Output Logic High Output Logic low Transition Times Rise Time Fall Time Symmetry or Duty Cycle Operating Temperature ordering option Symbol fO (+3.3V) (+5.0V) VDD VDD IDD 0/70 ˚C 0/70 ˚C -40/85 ˚C -40/85 ˚C VOH VOL VOH VOL tR tF SYM Minimum 77.76 3.15 4.75 Typical 3.3 5.0 Maximum 180 3.45 5.25
