Oscillators
Oscillators are electronic circuits designed to generate stable waveforms of waves with a specified frequency and amplitude. Oscillators are commonly used for radio transmission and reception, signal generation, clock synchronization, and other communications technology related devices. Oscillators are also often used in electronic musical instruments, sound effects, and timing applications to control the rate of frequency oscillations.
578R260CTT Application Field and Working Principle
The 578R260CTT is an oscillator from Vectron International. It is designed for use in high speed reference and memory applications. The main features of the oscillator include wide frequency range up to 4 GHz, wide supply voltage range of 1.6V to 2.8V, low total jitter, and low power consumption.
The 578R260CTT is based on an on-chip temperature-compensated crystal oscillator (TCXO) circuit. The TCXO circuit uses an external crystal to generate a highly stable reference signal. The signal is used to control the frequency of the oscillator. As the temperature changes, a thermistor within the TCXO circuit adjusts the frequency of the oscillator, providing temperature compensation.
The 578R260CTT features a 1.8V LVCMOS compatible output. The output has enable/disable control for low power consumption. The oscillator also features a selectable alternative frequency output for further flexibility. The 586R260CTT is ideal for applications where high speed accuracy and stability are required, such as DDR reference clocks, Baseband references, high speed network applications, and SerDes timing references.
