The Connor Winfield
VKB41B2, VKB42B2 and
VKB43B2 are hermetically
sealed surface mount 3.3V
Voltage Controlled Crystal
Oscillators (VCXO) with the
enable / disable function on
pad 2. The VKB41B2,
VKB42B2 and VKB43B2 are
designed for phased lock loop
applications requiring low jitter
and tight frequency stability.
