SMD TCXO ASTXR-12-26.000MHz-512883 ESD Sensitive Pb RoHS / RoHS II Compliant Moisture Sensitivity Level (MSL) – 1 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.
