SMD TCXO

ASTXR-12-26.000MHz-511911

RoHS / RoHS II Compliant

ESD Sensitive

2.5 x 2.0 x 0.8mm SMD

Moisture Sensitivity Level (MSL) – 1

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.
