The CY2302SC-1 is a frequency synthesizer that works as a fractional-N PLL and is part of the Cypress lineup of clock and timing solutions. It includes a low-jitter clock synthesizer, a 10 bit is digital-to-analog converter, and a voltage-controlled crystal oscillator. This clock synthesizer is ideal for consumer, communication, and industrial applications that require low jitter, wide dynamic frequency range, excellent spur suppression, and low power consumption.

The oscillator’s wide frequency range makes it suitable for the generation of clocks, data, and other information from various consumer, communication, and industrial applications. The oscillator’s frequency range is from 10 MHz to 1.04 GHz, and from 10 MHz to 11 GHz in low power mode. It has a stand-by current of less than 20 µA, making it one of the most efficient clock generators available in the market.

The oscillator’s primary working principle is to convert digital information into an analog signal to generate clocks of varying frequency. This is achieved by using a Fractional-N phase-locked loop (“PLL”) and a voltage-controlled crystal oscillator “VCXO”. The output frequency of the oscillator is selected by the user by providing a input voltage. The VCXO then generates an analog signal at the desired frequency. The PLL, then divides the input signal to match the output frequency.

The core of the oscillator consists of a CMOS phase-locked loop (“PLL”) and a voltage-controlled crystal oscillator (“VCXO”). The PLL is used to match the output frequency with the desired frequency from the user-defined range 10 MHz to 11 GHz. The VCXO is used to produce a high precision analog signal with a very low jitter. The oscillator’s jitter performance is superior to most other clock generators available on the market, achieving jitter levels below 100fs.

The oscillator also features excellent spur suppression. This is achieved by use of a second PLL and a low-power signal generator. The oscillator also has very fast frequency switching time of 100 ns, enabling it to change frequency quickly in response to changes in the user’s environment.

The oscillator is available in various packages, including SMT and through-hole packages. It can also be used in various industrial applications and is compatible with standard CMOS logic levels. The oscillator is lead-free and is compliant with RoHS.

The CY2302SC-1 is a superior fractional-N PLL clock synthesizer with excellent jitter and spur suppression performance. It is suitable for various consumer, communication and industrial applications where high precision, low power, and wide frequency range are required. Its fast frequency switching time makes it ideal for applications where fast frequency switching is required.
