DESCRIPTION
'GPQN' series oscillators are a precision frequency control component,
providing a LVDS output VCXO with low current consumption, a wide
frequency range with an integrated phase jitter performance of 0.6ps
r.m.s. The part is available in two industry-standard packages, 7 x
5mm SMD and 5 x 3.2mm SMD.
