Oscillators: AX7MCF1-420.0000TAn oscillator is an electronic instrument generating a periodic, oscillating signal without input from a source external to the device. It usually features a control input and an output amplitude control. Oscillators come in a variety of shapes and sizes, the most common being the PCS oscillator, also known as a Quartz Crystal Oscillator. This type of oscillator is widely used in RF, wireless and telecommunications applications. Oscillators are used to maintain a stable frequency for data and analog signal transmission.The AX7MCF1-420.0000T oscillator from Axiomtek is a Quad-Band PCS oscillator designed for IS-95, CDMA, WCDMA, GSM and 3G/4G applications. The AX7MCF1-420.0000T utilizes an advanced MEMS oscillator technology to achieve outstanding frequency stability and repeatability, while consuming a significantly lower current compared to conventional quartz crystal oscillators. The device incorporates a hermetically sealed quartz crystal for enhanced reliability and to minimize any potential environmental influences.The AX7MCF1-420.0000T oscillator offers excellent frequency stability over temperature of +/-30ppm from -40 to +105 degrees Celsius and is available in a variety of output formats including LVCMOS, SMD, and TTL. Due to its wide operating temperature range and superior performance characteristics, the AX7MCF1-420.0000T is well suited for both consumer- and industrial-grade telecom applications.The working principle of the AX7MCF1-420.0000T oscillator is similar to other oscillators. It is based on the feedback loop of a Self-Oscillating System. An oscillation source is used to generate the input signal. This signal is then filtered and amplified to create an oscillating output. Through a feedback loop, this output signal is passed back to the oscillation source, which then adjusts the input signal and rebalances the oscillation cycle. The AX7MCF1-420.0000T can be used in a wide variety of applications, including radio frequency (RF) and wireless communication, IS-95 based CDMA applications, 3G/4G LTE applications, and other digital/analog telecom applications. Its superior frequency stability makes it ideal for applications where long-term accuracy and stability are required.In conclusion, the AX7MCF1-420.0000T is a high-performance MEMS-based oscillator from Axiomtek, suitable for telecom applications requiring superior frequency stability and repeatability over extended temperature ranges. With its low current consumption and hermetically sealed quartz crystal, the AX7MCF1-420.0000T is designed for long-term use in harsh industrial environments. It is an ideal choice for controlling the frequency of wireless data transmission in CDMA and other telecom equipment.
