DESCRIPTION
'HTQF' series oscillators have been developed as a precision
frequency control component, providing a CMOS output clock
oscillator with low current consumption, wide operating frequency
range and an integrated phase jitter performance of 1.0ps r.m.s. The
part is available in two industry-standard packages, 7 x 5mm SMD
and 5 x 3.2mm SMD.
