ESD Sensitive Moisture Sensitivity Level (MSL) 1 OERIEW: 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 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 t 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 FEATURES: APPLICATIONS: GPS Excellent phase ise performance Smartphone Low power consumption PND Miniature size: Communications RoHS compliant Consumer electronics Temperature stability choices are ±0.5 to ±2.5 depending on Wi-Fi operating temperature range WiMAX/W-LAN STANDARD SPECIFICATIONS: Parameters Frequency Range Supply oltage (dd) Current Consumption (@dd max) Operable Temperature Range Storage Temperature Range Initial Frequency Tolerance @+25 C±2 C at time of shipment Minimum Typical Maximum Units -40 52 3.3 2 +85 MHz ma ºC -40 +85 ºC ±1 ±1 ±0.5 ±2.5 0.1 1 / C 0.6 ±0.1 ±0.2 ±1 10 1.8 Reflow Drift Frequency Stability over Operating Temperature Range Frequency Slope (tested to a minimum of 1 freq. reading every 2 C over operating temperature range) Static Temperature Hysteresis (Frequency change after reciprocal temperature ramped over the operating range.
