The CDC925DL integrated circuit is a combination digital oscillator and crystal clock generator. This application specific IC offers outstanding performance with the integration of a quartz oscillator and an amplifier. Its tone harmonics are well below the standard threshold and it operates with high frequency accuracy and stability.

The CDC925DL is a two-stage, digitally-controlled oscillator. The first stage is composed of a quartz oscillator and an amplifier. The oscillator is tuned to a precise frequency and applies a signal to the amplifier. The amplifier amplifies the signal and provides the signal to the second stage. The second stage is a digital divider circuit that takes the amplified signal and divides it down to the required fraction of the original clock signal frequency. The frequency is then provided to application specific integrated circuits for various timing or clock needs.

The CDC925DL can generate output frequencies up to 1 GHz and enables easy integration of multiple clock signals. The total phase noise of the output clock is better than -100dBc/Hz at 1MHz offset. The robust design ensures a low jitter output signal providing high precision clock signals.

The CDC925DL provides many advantages such as low power consumption and low cost. It is stable over a wide temperature range and offers excellent longterm frequency stability, better than ±1 ppm. The inductance tolerance of the quartz crystal is typically ±500ppm. Due to the excellent phase-noise characteristics, it provides improved performance over conventional oscillators. It can be used in many different applications such as: clock generators, audio codecs, video codecs, amplifiers, frequency synthesizers and modulators.

The CDC925DL is ideal for many applications such as clock rate converters and phase-locked loop frequency synthesizers. It is suitable for clock synchronization, control, and calibration of audio, video and data sync systems. It also provides a high degree of customization, allowing the user to design their clocks and timing circuits to meet specific needs and requirements. The CDC925DL is a versatile and effective solution for providing precise clock signals to a wide variety of applications.

The CDC925DL is a versatile clock device with outstanding performance and cost-efficiency. It provides precise and stable clock deployment for many different applications. The excellent phase-noise characteristics, combined with the low-power consumption, makes it an ideal choice for clock synchronization, control and calibration.
