EURO QUARTZ XO44 Series Oscillators 11.4 x 9.6mm SMD HCMOS Industry-standard hermetically-sealed package Frequency Range 20kHz to 130MHz Tristate (Enable/Disable) function as standard Supply voltage range 1.8, 2.5, 3.3 or 5.0 Volts OUTLINE & DIMENSIONS DESCRIPTION XO44 oscillators consist of a TTL/CMOS-compatible hybrid circuit with a miniature quartz crystal packaged in a low-profile, industrystandard package. The high quality design and materials employed provide a highly reliable clock oscillator in a miniature package while mass production methods ensure that the XO44 provides a costeffective oscillator solution.

(to reach 90% amplitude at 252C) 5ppm max. In first year 10ps typical 100ms max. 100ns max. Ageing: Phase Jitter RMS: Enable Time: Disable Time: Tristate Function (Pad 1): Output (Pad 3) is active if Pad 1 is not connected or a voltage to Pad 1 is 'HIGH'. Output is high impedance when 'LOW' or GROUND is applied to Pad 1. * Frequency stability is inclusive of calibration tolerance at 25C, frequency change due to shock & vibration, 10 supply voltage variation and stability over temperature range.
