Also, the device can be used for systems that require jitter-free performance such as clock generation for HDTV equipment, DSC and DVC decoders, digital receivers, or other video- or audio-related systems. The CS2300CP-DZZR is also ideal for any application requiring dynamic timing such as in digital video, digital TV, medical, and avionics systems.

Features

The CS2300CP-DZZR features low power consumption, a wide frequency-range output (2-335 MHz), a minimum of 16 independent output signals, a spread-spectrum frequency modulation for minimizing EMI, and a high frequency stability utilizing on-chip temperature compensation. Additionally, it has a built-in phase-locked loop (PLL) for voltage control, providing the ability to reduce the supply voltage and increase the system\'s energy efficiency.

This programmable clock generator also features many features to ensure the most accurate and reliable output timing. An on-chip voltage control allows users to adjust the output frequency in steps as small as 1 KHz and as large as 8 MHz. Moreover, it has an I 2C interface, allowing external control and adjustment, and it supports MCLK, BCLK, and PPMP outputs, which are used in applications related to audio, video, and data communication.

Working Principle

The CS2300CP-DZZR follows a basic working principle of a Phase-Locked Loop (PLL). It obtains precision clock signals from a single input pin, referred to as REFP or the reference frequency. It then multiplies this signal by an internal VCO (Voltage Controlled Oscillator). By multiplying the signal, the VCO generates multiple output signals that are proportional to the reference frequency. This process is known as Frequency Synthesis.

In more detail, the internal PLL continuously compares the output signal from the VCO to the reference frequency and adjusts the VCO frequency whenever there is a discrepancy. The CS2300CP-DZZR has frequency tripling and fractional frequency divisions, to further reduce the frequency difference between the reference signal and the output signal. This ensures that the output signals are locked in phase with the reference signal.

The CS2300CP-DZZR also has numerous integrated features to lower jitter and reduce power consumption. A power-saving shutdown mode is included to reduce current draw while not in operation. The CS2300CP-DZZR also has a Zero-Delay Mode (ZDM) for synchronization between multiple outputs, which increases the accuracy and reduces jitter even further. Additionally, the CS2300CP-DZZR features an on-chip temperature compensation circuit, which ensures that the output frequency remains stable over varying temperatures.

Conclusion

The CS2300CP-DZZR is a low-jitter, ultra-low-power, compact clock generator used in a variety of applications, including broadband and wireless communications, consumer audio and video systems, medical equipment, and data communications. It provides customers low-power, single-chip solutions that can improve system performance and save board space, featuring full WiFi, Bluetooth, and audio applications compatibility, flexibility, and stable output timing. This device is equipped with a Phase-Locked Loop (PLL) and multiple features to reduce jitter and power consumption, making it an ideal choice for applications requiring accurate and robust timing.
