Description

f_o

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 3^rdovertone

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.
