STANDARD SPECIFICATIONS:
Abracon’s ASTXR series of Temperature Compensated Crystal Oscillators are based on an Advanced-Analog Temperature Compensation
Integrated Circuit, incorporated with Rakon’s Precision TCXO processing techniques.
This composite enables exceptional frequency stability over temperature (≤±0.50 ppm over -40°C to +85°C). Additionally, high-resolution
screening algorithms are employed during the production verification process, ensuring that 100% of these devices are fully compliant to the
stringent frequency stability specifications.
For Power Sensitive applications, the ASTXR series provides the ability to preserve consumed power by placing the device in shut-down mode;
when not used. This series of devices are ideally suited for GPS and other mobile applications where performance, size, cost and power
management are of critical importance.

Note:
1. Parts should be shielded from drafts causing unexpected thermal gradients. Temperature changes due to ambient
air currents on the oscillator can lead to short term frequency drift
2. Specified for load stated in the Oscillator Output section at +25°C
3. AC-Coupled outputs require an external capacitor, ≥ 1nF recommended
4. Frequency shift ≤1ppm after reliability test conditions (see section 7.0)
