CMX309FBC1.544M-UT Application Field and Working PrincipleOscillators are electronic devices that help generate an oscillatory waveform through the regular repetition of electrical signals. The device is widely used in various industrial and commercial applications, including automotive, telecommunications, medical, and aerospace equipment. The CMX309FBC1.544M-UT is an example of such an oscillator. It is a low power programmable oscillator designed to provide reliable and stable frequency performance with 15 different output frequencies available.The CMX309FBC1.544M-UT oscillator is a two-pin device that operates with a single 3.3V power supply. It has a frequency range of 1.544MHz to 15.728MHz and an output waveform output type of TTL, CMOS, or HCMOS. The device has a temperature range of - 20°C to + 70°C and a low standby current of 350uA. It operates in four different modes: normal frequency mode, fixed frequency mode, power save mode, and suspend mode.In normal frequency mode, the CMX309FBC1.544M-UT oscillator operates at a standard frequency of 1.544MHz. The output pin is controlled by a frequency settings register, a control register, and a control input pin. The frequency settings register is used to select the desired output frequency, and the control register and input pin are used to control the device’s operating modes. The oscillator can also be programmed with a host system for direct control.In fixed frequency mode, the oscillator is set to a predetermined frequency and is locked in that frequency. This mode is used when precise frequency is required. In power save mode, the oscillator operates at minimal power and can be shut off if not in use. Suspend mode will disable the oscillator, allowing a host system to take control of the oscillator and control its output frequency.The CMX309FBC1.544M-UT oscillator is suitable for applications such as microcontroller clock sources, embedded systems, industrial automation, and consumer electronics. Its low power consumption and broad operating temperature range make it an ideal choice for battery operated devices. It is also used in communications equipment, including DSL modems, Wi-Fi routers, and cordless phones, as well as digital audio players, remote control devices, and digital cameras.The CMX309FBC1.544M-UT oscillator offers excellent frequency stability and high performance. Its frequency settings register and control input pin allow for both manual and automated control of the output frequency. The device is also RoHS compliant and meets various industrial standards, which makes it an ideal choice for various industrial applications.
