Description
fo
Vectron’s C-TYPE Crystal Oscillator (XO) is
quartz stabilized square wave generator with a
CMOS output, operating off a 1.8, 2.5, 3.3, or 5.0
volt supply.
Output
Buffer /
Disable
The C-TYPE uses fundamental or 3rd overtone
crystals resulting in low jitter performance,
typically 0.5ps rms in the 12 kHz to 20MHz band.
Also a monolithic IC, which improves reliability
and reduces cost, is hermitically sealed.

C-TYPE 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 C-TYPE, 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.
