VCS3 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 VCS3, 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.

Suggested IR profile
Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow
conditions, Table 9 shows max temperatures and lower temperatures can also be used e.g. peak
temperature of 220C.
