Description
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.
The C-TYPE uses fundamental or 3
rd
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.
