COR PORATI ON
ANALOG TCXO
DUAL-IN-LINE CRYSTAL OSCILLATORS
3.3 to 5Vdc - 10MHz to 80MHz
Description
The Q-Tech Analog TCXO encompasses state-of-the-art
oscillators with low phase noise, jitter, and tight temperature
stability. The TCXO is available in a DIP (QT3003), SMD
(QT3013) or Gull Wing (QT3023) package and as a square or
sine wave oscillator.
A flexible design allows Q-Tech Corporation to offer a
variety of choices of output standard, power and load.
Based on this flexibility, Q-Tech welcomes specifications
with parameters other than standard.
Low G-Sensitivity AT-Cut Crystal utilized in the design
allows to get 1PPB/G.
The reliable construction of this design qualifies it for
stringent environmental applications.

Other Design and Test Options
• Supply voltage +3.3Vdc to +5Vdc
• Output power -10dBm to +13dBm into 50Ω
(see note 1)
• Harmonics better than -20dBc (see note 2)
• Sub-harmonics better than -30dBc (see note 3)
• Amplitude stability versus temperature to
within ±1% (see note 4)
• Phase Noise and Jitter built to specification
including static and vibration.
• Low supply current
• QCI tests
• Tight frequency stability versus temperature,
supply voltage, and load variations
• Low g-sensitivity and low phase noise

Notes:
1. The output level is determined by the supply
voltage, load, and package size.
2. A specified harmonic level of -20dBc is easily
achievable. The typical harmonics of Q-Tech Sine
Wave source are better than -25dBc.
3. Sub-harmonic level is determined by frequency
multiplication method, supply voltage, output power,
and input current.
4. Typical amplitude stability over temperature is
±10% or less.
5. Typical spurious level is better than -90dBc over
the spectrum of 100kHz to 1GHz.
