Oscillators

Oscillators are often used for timing applications. Timing applications, in most cases, are highly dependent on precise frequency generation. Thismeans that the oscillator must produce a precise output frequency. In addition to this, oscillators are also very important applications in the family of signal sources. This article will discuss the application field and working principle of the ASM-4.096MHz-ET oscillator.

Application Field

The ASM-4.096MHz-ET oscillator is ideal for a variety of applications, including timing modules in industrial equipment, communications systems, and general purpose signal sources in test and measurement. It is also well-suited for use in timing-related applications where highly accurate frequency control is required. In addition, due to its small size, low power consumption and low cost, the oscillator can be used in a variety of embedded systems where space constraints and power consumption are critical. It can also be used in portable applications such as wristwatchers and PDA.

Working Principle

The ASM-4.096MHz-ET oscillator operates by producing a sinusoidal signal at a frequency of 4.096MHz. This frequency is determined by an internal quartz crystal that is physically present within the oscillator, and the frequency is further refined by an on-chip digital divider circuit. This ensures that the frequency of the output signal remains highly stable, with very low phase noise and high precision. The oscillator is constructed on a 4-pin, surface mount ceramic package, and it uses a 5V DC supply voltage. The supply voltage is used for the on-chip oscillator circuitry, and it also supplies power to the quartz crystal for frequency stabilization.

The output of the ASM-4.096MHz-ET oscillator is a sine waveform at 4.096MHz. The sine waveform produced by the oscillator is maintained at a very high accuracy and stability with a typical phase noise of -80dBc/Hz at 100kHz offset. The maximum wave distortion is typically less than 0.5%, and the lock-in time is typically less than 50µs. The output impedance of the oscillator is 50Ω, and the output voltage swing is typically +1.6V to -1.6V, with a maximum output power of +5dBm.

In conclusion, the ASM-4.096MHz-ET oscillator is an ideal choice for a variety of timing and general signal source applications, where precise frequency control and high stability are required. Its small size, low power consumption and low cost make it suitable for use in embedded systems and portable applications, as well as in industrial and communications systems. The on-chip digital divider and quartz crystal provide highly stable operation with very low phase noise and excellent accuracy.
