1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.

2. Figure 3 defines these parameters. Figure 4 illustrates the operating conditions under which these parameters are

tested and specified. For Fo>90MHz, rise and fall time is measured 20 to 80%.

3. Symmetry is measured defined as On Time/Period.

4. Includes calibration tolerance, operating temperature, supply voltage variations, aging and shock and vibration.

5. Output will be enabled if enable/disable is left open.

VCE1 Data Sheet

Enable/Disable Functional Description

Under normal operation the Enable/Disable is left open or set to a logic high state. When the E/D is set to

a logic low, the oscillator stops and the output is in a high impedance state. This helps reduce power

consumption as well as facilitating board testing and troubleshooting.

Tri-state Functional Description

Under normal operation the tri-state is left open or set to a logic high state. When the tri-state is set to a

logic low, the oscillator remains active but the output buffer is in a high impedance state. This helps

facilitate board testing and troubleshooting.

Handling Precautions

Although ESD protection circuitry has been designed into the the VCE1, proper precautions should be

taken when handling and mounting. VI employs a Human Body Model and a Charged-Device Model

(CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on

the circuit parameters used to define the model. Although no industry wide standard has been adopted

for the CDM, a standard HBM of resistance = 1.5kohms and capacitance = 100pF is widely used and

therefore can be used for comparison purposes.
