No output (standard option) 2. 2.2V for min Vs>2.4V 3. 2.7V for min Vs>3.0V Maximum load current (mA) = Vref/10 For manual frequency adjustment connect an external 50k potentiometer between pad 1 (Reference Voltage) and pad 4 (GND) with wiper connected to pad 10 (Voltage Control). Please specify reference voltage as part of the ordering code. Standard Voltage Control Ranges: Without Reference Voltage Vs=3.3V 1.65V1.0V With Reference Voltage Vs=0V to Vref Linearity: 1% max Slope: Positive Input Impedance: 100k min Modulation Bandwidth: 2kHz min A. Standard Pulling Adjustment: 5ppm min, frequency 20MHz 7ppm min, frequency >20MHz B. No frequency adjustment initial calibration 25C 1.0ppm C. High Pulling 10ppm to 20ppm can be available depending on frequency and stability options (please contact an IQD Sales Office) Output Details HCMOS Output Compatibility Drive Capability 15pF Rise and Fall Time 8.0ns max Duty Cycle 45/55% VoL: <10% Vs VoH: >90% Vs Output Control Tri-state Operation: Logic 1 (>60% Vs) or no connection to pad 8 enables output Logic 0 (<20% Vs) to pad 8 disables output The tristate control (enable) pin has a internal 100k pull up resistor which allows the pin to be left unconnected if not required. When in tristate mode, the output stage is disabled, but the oscillator and compensation circuit are still active (current consumption typ. 1.0mA).
