HIGH STABILITY DIGITAL TCXO
Q-TECH
CORPORATION
SURFACE MOUNT CRYSTAL OSCILLATORS
3.3 to 5Vdc - 1MHz to 125MHz
Q-Tech’s High Stability Digital TCXO is a high reliability
signal generator that provides an HCMOS output. The TCXO
is available in a Surface Mount (SMD) package.
Description
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
guarantees 1PPB/G or better. The reliable construction of this
design qualifies it for stringent environmental applications.

• Supply voltage +3.3Vdc to +5Vdc
• 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
• Low spurious (see note 3)
• Low frequency aging, Allan Variance
• High-shock resistant
Notes:
1. The output level is determined by the supply
voltage, load, and package size.
2. Typical amplitude stability over temperature is
±10% or less.
3. Typical spurious level is better than -100dBc
over the spectrum of 100kHz to 1GHz.
4. Guaranteed by design, can be tested by customer
request.
5. TCXO with frequencies higher than 50MHz,
have amplitude more sensitive to load and it may
be lower than standard.
