5.0V Surface Mount
5.0mm x 7.5mm Oscillators
VKA51A2, VKA52A2, VKA53A2
VCXO
The Connor-Winfield, RoHS compliant, VKA51A2,
VKA52A2, and VKA53A2 are hermetically sealed,
Surface Mount, 5.0V Voltage Controlled Crystal
Oscillators (VCXO) with the enable/disable function
on pad 2. The VKA51A2, VKA52A2, and VKA53A2
are designed for phased lock loop applications
requiring low jitter and tight stability. The surface
mount package is designed for high-density
mounting and is optimum for mass production.

Notes:
1. Referenced to (Fo) measured with control voltage @ 1.65Vdc. Inclusive of frequency vs. temperature stability, supply voltage change, load change, shock and
vibration, 15 years aging.
2. Referenced to Fo at T=25°C Positive Slope.
3. The Output is enabled with no connection on the enable pin. Output is at high impedance when disabled.
