CY23FP12OXC

The CY23FP12OXC is a high-performance frequency synthesizer and clock generator from Cypress Semiconductor. Cypress’s core competence in this device is the ability to provide a wide variety of clock outputs – covering a range from 1MHz to 220MHz – for any given input frequency. Commonly used in set-top boxes, medical equipment, and other consumer electronics, the CY23FP12OXC is an excellent choice for applications needing flexible and efficient frequency synthesis.The CY23FP12OXC consists of two main components: an input stage, which accepts a number of input frequencies, and a VCO (Voltage Controlled Oscillator), which is responsible for providing the clock output, given the input frequency. The input stage contains a pre-programmed bank of input frequencies and an oscillator control logic block, which provides the necessary logic signals to start and control the VCO. Additionally, the input stage provides the necessary feedback signals to the VCO to ensure output stability.The VCO, on the other hand, is responsible for generating the necessary frequency output from the input frequency. In order to do this, it contains a varactor and a LC-tank circuit. The varactor is responsible for controlling the frequency of the output by changing the capacitance of the LC-tank circuit. In turn, this change in capacitance alters the resonant frequency of the tank circuit, resulting in the desired frequency output. Additionally, the VCO contains control logic which ensures that the output frequency remains within the specified parameters, even when faced with varying input frequencies.To ensure maximum performance, the CY23FP12OXC features built-in features within the VCO. For example, it features circuitry designed to minimize jitter and spurious output. Additionally, it features a wide range of frequency output changes, as well as programmable equalization of the output swing. These features ensure that the output frequency is always kept within the specified tolerance range, even with varying input conditions.Overall, the CY23FP12OXC is a great option for applications needing a high-performance clock or frequency synthesizer. Its flexible frequency selection, low jitter and spurious outputs, and wide range of frequency outputs make it perfect for a variety of needs. Its relatively small size and low power consumption also make it ideal for applications requiring a compact and efficient solution.
