ESD Sensitive
Pb ^{RoHS / RoHS II Compliant}
2.5 x 2.0 x 0.8mm SMD
OVERVIEW:
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.
