The CY25403FSXC is a clock generator with programmable output frequencies from 1MHz to 133MHz, allowing designers to configure the output clocks with a wide range of frequencies. It contains a two output clock generator IC that is ideal for applications in Consumer Electronics, Computing and Communications.

The CY25403FSXC features a PLL-based low-power design with an integrated voltage-variable frequency control algorithm that maintains the best frequency accuracy with minimal power consumption. The PLL also helps in providing clean, jitter-free output signals over a wide frequency range. As the clock output frequency can be programmed through a simple serial interface, the CY25403FSXC can be used in a variety of applications such as PC, TV, network equipment, VoIP systems and automotive electronic devices.

Working Principle

The CY25403FSXC uses a two-output clock generator IC with a low-power PLL for generating clock signals in a wide range of output frequencies. The CY25403FSXC includes an on-chip voltage-variable frequency control (VVFC) algorithm for maintaining the best frequency accuracy with minimal power consumption. With the VVFC algorithm, the CY25403FSXC can accurately generate a wide output frequency range with minimal jitter.

The CY25403FSXC also includes a thermal compensation circuit to provide additional frequency accuracy. The thermal compensation circuit maintains the same output frequency even if the ambient temperature changes. The thermal compensation can reduce the temperature-induced frequency drift of the generated clock signal by up to 66%.

The CY25403FSXC can be programmed to generate clock frequencies with up to ±50ppm accuracy. This allows it to provide reliable and accurate clock signals for applications requiring minimum jitter and tolerance. The CY25403FSXC also has a programmable slew rate control, which allows the designer to adjust the output frequency according to the application requirements.

To simplify the clock design, the CY25403FSXC includes a number of features. The CY25403FSXC includes an integrated voltage regulator, on-chip power saving modes, and integrated buffer memory for storing frequency and configuration parameters. The on-board temperature compensation circuit ensures the output frequency remains constant between ambient temperatures.

In addition, the CY25403FSXC can be configured using a simple serial interface and is compatible with a wide range of microcontrollers and controllers. This reduces the need for large PCB space and simplifies the design process.
