The SMBN-033333-7BL4T00 is a RoHS compliant SMD-7050 Oscillator (XO) manufactured by Aker. The oscillator has a frequency range from 100 kHz to 250 MHz and a maximum frequency tolerance of ±50 ppm at +25°C. It is very small, measuring only 0.50 x 0.50mm. This makes it ideal for space-constrained applications such as mobile phones, laptops, and PDAs. It requires an operating voltage of only 1.2V, making it very power-efficient. It also has a low current consumption (2.5 mA max) and very low EMI levels. It has a wave stability of less than ±2.5 ppb/°C and a typical phase noise of -122dBc/Hz @ 1KHz offset. Aside from these features, the SMBN-033333-7BL4T00 has additional features that make it a desirable choice for high-frequency applications such as LTE 4G/3G/2G, Wi-Fi, Zigbee, and Bluetooth.
