Output Load TTL: 2 TTL gates CMOS: 15pF
Rise/Fall Times TTL: 6ns max., 4ns typical Measured between 0.4V to 2.4V CMOS: 6ns max., 4ns typical Measured between 20% to 80% of wave form, (CL = 15pF)
Duty Cycle: 50%±10% standard, 50%±5% is available, add 'S' to part number
Integrated Phase Jitter: 200fs max. (12kHz to 20MHz)
Start-up Time: 10ms max., 5ms typical
Current Consumption: 10~45mA, freq. dependant e.g. 27MHz: 10mA @ 3.3V 27MHz: 20mA @5.0V
Linearity: 6% typical, 10% max
Modulation Bandwidth: 10kHz min. Measured at -3dB with V control at 1.65V or 2.5V
Input Impedance: 1MΩ typical
Slope Polarity: Monotonic and positive (An increase of control voltage increases output frequency.)
