XLH730030.000000X

Oscillators

An oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal, typically as an input to an amplifier. XLH730030.000000X is an oscillator from Exar Corporation. It is designed to provide solutions for digital audio applications including video game consoles, digital audio players, MP3 players, interfaces and controllers, A/V receivers, low power audio transports, and other portable devices requiring precision timing.

XLH730030.000000X Application Field

The XLH730030.000000X oscillator from Exar Corporation is designed for audio applications. It is optimised for low jitter (down to 15 femtosecond) and low power (1.8 - 3.6V) performance. It is AEC-Q100 qualified and production parts come with an integrated TCXO solution for improved accuracy. This oscillator is ideal for applications such as game consoles, digital audio players, MP3 players, and low power audio transports.

XLH730030.000000X Working Principle

The XLH730030.000000X oscillator is based on a patented technology consisting of a quartz resonator and a silicon integrated circuit. A main component is a quartz crystal oscillator controlled by a low-power circuit called a feedback oscillator. The quartz resonator’s frequency determines the oscillating frequency of the oscillator.The oscillator is supplied with an input voltage to the integrated circuit and the oscillator produces an alternating current (AC) signal as output. The frequency of the output signal is calculated from the input voltage and the resonant frequency of the quartz resonator.The frequency can also be fine-tuned depending on the application requirements. The feedback oscillator requires very low operating current and can operating at the same frequency for long periods of time without losing accuracy. The frequency stability of the oscillator can also be adjusted to ensure consistent output over time.
