Oscillators are widely used in a variety of integrated electrical systems such as audio, video, digital signal processing (DSP) and measurement systems. The CCHD-957-25-49.152 oscillator is a member of this family of devices, and it is designed to be used in applications requiring high frequency stability, low jitter and low phase noise.

A CCHD-957-25-49.152 oscillator is an integrated timing device that can produce a stable output frequency from a fixed input voltage. It contains a quartz crystal resonator oscillator that produces an ac signal based on the fundamental frequency of the quartz crystal. This ac signal is amplified and converted to a square wave by a logic circuit. The logic circuit contains a comparator, counter, and divider that produces the desired output frequency from the crystal frequency.

The CCHD-957-25-49.152 oscillator has a frequency range of 9.57 – 25.49 MHz, a resolution of 1 Hz, a power consumption of 1.2 W, and an input voltage of 3.3 – 5.5 V. The main features of the CCHD-957-25-49.152 oscillator include low jitter (30 ps max) and low phase noise (100 dBc/Hz @ 10 kHz from carrier). The quartz crystal resonator oscillator is encapsulated in a small hermetic package which helps to protect it from environmental conditions such as temperature, shock and vibration.

The CCHD-957-25-49.152 oscillator is used in a wide range of applications, such as clock and data recovery, clock and data distribution, clock synchronization, timing and control, frequency synthesizers,and modems. In clock and data recovery, it is used to generate a stable, low jitter clock signal from an incoming data stream to recover the data. In clock and data distribution, it is used to transmit a stable, low jitter clock signal to multiple other devices. In clock synchronization, it is used to synchronize two or more clocks in order to keep them running in phase. In frequency synthesizers, it is used as a reference frequency source for frequency synthesis. It is also used in modems to generate a stable low jitter clock to recover data from the incoming data stream.

The working principle of the CCHD-957-25-49.152 oscillator is based on the crystal resonator oscillator. The crystal resonator oscillator consists of a quartz crystal resonator, an amplifier and a logic circuit that produces a square wave output from the ac signal. The quartz crystal resonator is a thin piece of quartz crystal that vibrates at a frequency determined by its physical parameters such as size, shape, and thickness. The amplifier is used to amplify the ac signal to the level required by the logic circuit. The logic circuit contains a comparator, counter and divider which produce the desired output frequency from the crystal frequency. The output frequency is then smoothed by a low pass filter to reduce the jitter before being output.

In conclusion, the CCHD-957-25-49.152 oscillator is a high-performance device designed for applications requiring high frequency stability, low jitter, and low phase noise. It is used in a wide variety of integrated electrical systems, such as audio, video, DSP, and measurement systems. The main features of the oscillator include a wide frequency range, low jitter and low phase noise. It is based on the crystal resonator oscillator, which consists of a quartz crystal resonator, an amplifier and a logic circuit. The output frequency is then smoothed by a low pass filter to reduce jitter. The CCHD-957-25-49.152 oscillator is a reliable, economical and accurate device for timing and control applications.
