CY23S05SXC-1 is a high-performance low-jitter frequency synthesis Clock Generator designed to meet modern mobile, consumer, computing, and communication system requirements. CY23S05SXC-1 utilizes the advanced PLL technology and provides the flexibility of programming the outputs via the pin-selectable options. It is available in an ultra-small 3.2mmx2.5mm WTFN package and is used in a wide range of applications such as mobile phones, automotive infotainment systems, digital video recorders (DVRs), set-top boxes, etc.

The application field of CY23S05SXC-1 is mainly in consumer electronics, communications applications, industrial and automotive applications. It is a multi-output clock generator and provides low-jitter accuracies for each output frequency. It provides multiple frequency options for the output clock, ranging from 8 kHz to 72MHz for output frequencies. It can be used for clock generation and frequency synthesis in many consumer and communication systems.

The working principle of CY23S05SXC-1 is based on Precision Feedback Architecture (PFA) technology. This technology ensures high accuracy, low jitter and low phase noise for each output and provides the necessary flexibility of programming the outputs. It comprises of a voltage controlled oscillator (VCO), a programmable phase frequency detector (PFD) , and a programmable loop filter.

The VCO is the heart of the device, acting as the frequency source. The VCO output is compared by the PFD to a stable reference input frequency and the PFD automatically adjusts the control voltage as a function of the frequency error. The loop filter smoothens out the control voltage and provides a steady reference clock frequency across the operating temperature and voltage variations. The loop filter also provides the necessary flexibility of programming the output frequencies.

CY23S05SXC-1 also includes the necessary internal circuitry for programming the reference frequency and output frequency pins. The PLL can lock to an internal or external reference input, directly from a CMOS compatible source or from a crystal oscillator. The frequency selection can be achieved by programming the output and reference/input frequency pins.

In conclusion, CY23S05SXC-1 is a high-performance frequency synthesis Clock Generator used for a wide range of applications such as mobile phones, automotive infotainment systems and set-top boxes. It utilizes the advanced PLL technology and the Precision Feedback Architecture (PFA), providing low jitter accuracies for each output frequency. This device also provides the flexibility of programming the outputs via pin-selectable options.
