Application Field

CDCE949PWG4 can be used to generate clocks for applications such as data routers, switches, wireless base stations, and embedded controllers. It is suitable for applications that require precise timing and low jitter including data communications, security systems, cellular networks, and PCI Express buses. The device is also suitable for applications that require the generation of four low jitter clocks such as microprocessor based designs. The device is designed to be a highly flexible and precise clock generator, providing four low noise clocks with very low jitter.

Working Principle

CDCE949PWG4 operates by using a Phase-Locked-Loop (PLL) circuit. The PLL circuit comprises an oscillator, a phase detector, low pass filter, and voltage control oscillator (VCO). The oscillator generates a reference signal which is fed to the phase detector. The phase detector compares the phase of the reference signal to the phase of the feedback signal from the VCO and generates the error signal. The low pass filter smoothes the error signal and amplifies the low frequency components while suppressing the high frequency components. The output of the filter is converted to a voltage which is then used to control the frequency of the VCO. The output of the VCO is the clock signal which is outputted by the device.

The device has a wide range of output frequencies and can be programmed to generate the desired clock frequency. The device also has a wide range of clock divider ratios, allowing it to generate a variety of clock frequencies with different output sizes. The device also has the flexibility to be used in a wide variety of applications, providing a single source for four low noise clocks.

CDCE949PWG4 is a highly reliable and versatile solution for generating multiple clocks with low jitter. It has a wide range of output frequencies and can be easily programmed to generate the desired clock frequencies. The device is also suitable for applications with high timing accuracy, providing a single source for four low noise clocks.
