The CDCF2509PWR is a Clock/Timing Application Specific product optimised for low power applications. It is comprised of an embedded Charge Pump Regulated Voltage Reference, a digital Frequency Counter, a Voltage Regulator and a Digital Oscillator. This article will explain the application field of the CDCF2509PWR, and its working principle.

Application Field

The CDCF2509PWR is ideal for a variety of digital system applications such as digital communications, portable electronics and microprocessors. It is optimised for low power applications and offers very low total power consumption. The CDCF2509PWR features a wide range of operating frequencies and is suitable for both surface mount and through-hole applications.

The CDCF2509PWR can withstand extreme temperatures and is designed to operate in high-dynamic ranging environments. Its designed input voltage range is from 0.45V to 6V and its output voltage range is from 0.45V to 10V. The CDCF2509PWR is also ideal for low-noise and low-EMI applications.

Working Principle

The CDCF2509PWR consists of an embedded Charge Pump Regulated Voltage Reference, a digital Frequency Counter, a Voltage Regulator and a Digital Oscillator. The Charged Pump Regulated Voltage Reference ensures low noise and high accuracy characteristics. The Digital Frequency Counter records the frequency of the oscillator by counting the rising and falling edges of the square wave output. The Voltage Regulator ensures stable operation of the oscillator and the Digital Oscillator produces a square wave output.

The CDCF2509PWR has three main operating modes: Frequency Mode, Voltage Mode and Digital Mode. In Frequency Mode, the frequency of the output is determined by the setting of the frequency counter. In Voltage Mode, the output is determined by the setting of the voltage regulator. In Digital Mode, the output is determined by the setting of the digital oscillator. The CDCF2509PWR is designed to detect power-on, power-off and reset conditions, ensuring that it is always in a stable state.

The CDCF2509PWR is designed to provide an extremely accurate and stable frequency output. It also features power-down control and low-power modes for even greater power efficiency. The CDCF2509PWR supports output frequency ranges from 24MHz to 1GHz and a wide dynamic range. It is also equipped with an integrated temperature sensor which ensures that the CDCF2509PWR operates reliably in any environment.
