'HTQN' Specification Low Jitter Oscillators

'HTQN' 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 0.6ps r.m.s. The

part is available in two industry-standard packages, 7 x 5mm SMD

and 5 x 3.2mm SMD.

Low jitter <0.6ps phase jitter

Wide frequency Range 10.0MHz to 245.0MHz

Low supply current <18mA at 50MHz

Supply voltage range 2.5V or 3.3Volts

Tristate function to conserve power
