SINE WAVE SOURCES
Q-TECH
Description
CORPORATION
DUAL-IN-LINE CRYSTAL CLOCK OSCILLATORS
5.0 to 15Vdc - 10Hz to 450MHz
The Q-Tech Sine Wave Sources encompasses state-of-
the-art sinewave source with low harmonic distortion
and a precise sinewave output.
A flexible design allows Q-Tech Corporation to offer
a variety of choices of output power and load. Based on
this flexibility, Q-Tech welcomes specifications with
parameters other than standard. An external trimming
capacitor option is available for applications that require
a tight frequency stability.
The AT-Cut crystal utilized in the design allows for
high stability for a particular temperature range
extending from -55ºC to +125ºC. For more information,
please refer to the stability vs. temperature on the
following page.
The reliable construction of these sinewave oscillators
qualifies them for more stringent environmental
applications. Military screening per MIL-PRF-55310,
Level B is available as an option.

power, and input current.
4. Typical amplitude stability over temperature is
±10% or less.
5. Typical spurious level is better than -60dBc over the
spectrum of 100kHz to 1GHz.

Substrate
Heat spreading occurs when heat flows into a material layer of
increased cross-sectional area. It is adequate to assume that
spreading occurs at a 45° angle.
The total thermal resistance is calculated by summing the
thermal resistances of each material in the thermal path
between the device and hybrid case.

The total thermal resistance RT (see figure 2) between the heat

• Theta junction to case (Theta JC) for this product is 24°C/W.
• Theta case to ambient (Theta CA) for this part is 106°C/W.
• Theta Junction to ambient (Theta JA) is 130°C/W.
Maximum power dissipation PD for this package at 25°C is:
• PD(max) = (TJ (max) – TA)/Theta JA
• With TJ = 175°C (Maximum junction temperature of die)
• PD(max) = (175 – 25)/130 = 1.15W
