DESCRIPTION
'HDQN' series oscillators have been developed as a precision
frequency control component, providing a LVDS output clock oscillator
with low current consumption, wide operating frequency range and
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.
