CY2SSTV850ZC is an integrated frequency synthesizer solution intended for a wide range of clock and timing applications. It features a variety of convenient and comprehensive features, including frequency range, phase noise, jitter, and spread spectrum clock outputs. It is provided as a fully integrated solution with an on-chip voltage regulator, power-on reset circuit, and on-chip high speed comparator. This makes it an ideal choice for applications requiring a clock generator, PLL, or frequency synthesizer.

The CY2SSTV850ZC was designed to meet the demanding performance requirements of many high speed clock and timing applications, such as high speed modems, high speed data converters, and network equipment. It is capable of generating a wide range of frequencies with low phase noise, jitter and spread spectrum clock outputs, making it suitable for applications that require low-noise, low-jitter clocks. The integrated voltage regulator, power-on reset circuit, and high-speed comparator enable the CY2SSTV850ZC to provide power efficient, robust and reliable clock generation in applications where the cost and complexity of an external voltage regulator is prohibitive.

The CY2SSTV850ZC is based on a fixed-frequency PLL architecture, where the output frequency is determined by the on-chip frequency divider. The input reference frequency is divided down to the desired output frequency by the on-chip frequency divider. The input reference frequency is divided down to the desired output frequency by the on-chip frequency divider. The PLL then multiplies the input reference frequency by a factor of N+1 to synthesize the desired output frequency on the VCXO (Voltage Controlled Crystal Oscillator) output.

The PLL also includes an integrated low distortion sigma-delta modulator (SDM), which is used to further improve the frequency accuracy and phase noise performance. The SDM allows the PLL to fine-tune the output frequency with a resolution of 1Hz. The SDM is controlled by programming the SDM control register and the PLL control register.

The CY2SSTV850ZC also features a spread-spectrum circuit, which is used to reduce spurious emissions from the clock signal. The spread-spectrum clock generator is capable of generating a spread-spectrum SQW output signal. The spread-spectrum clock generator has a wide range of adjustable parameters, including modulated frequency, modulation depth, center frequency and modulation type.

In addition to the voltage controlled frequency synthesis, the CY2SSTV850ZC also offers a programmable clock generator circuit, which is used to generate low-jitter, low-spurious clock outputs. The on-chip clock generator includes a selectable PLL loop bandwidth and programmable dividers, which allow for a wide range of clock frequencies to be generated, including high-frequency and low-jitter clocks.

The CY2SSTV850ZC is an ideal solution for a wide range of clock and timing applications.
