Description
Vectron’s VMP2 Clock Oscillator is a silicon
MEMS based stabilized square wave generator
with a CMOS output, operating off a 3.3V supply.
The VMP2 uses an internal compensation circuit
to improve temperature stability which produces
performance similar to quartz based products.

Enable/Disable Functional Description
Under normal operation the E/D is set to a logic high state or logic low state. When 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. When E/D is set to a logic high
state, the oscillator produces an output. Leaving the Enable/Disable pin open results in an indeterminate
output state.

Handling Precautions
Although ESD protection circuitry has been designed into the the VMP2, 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.

Suggested IR Profile
Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow
conditions. Figure 4 shows max temperatures and lower temperatures can also be used e.g. peak
temperature of 260C.
