The CY25100KZXC46 is a clock generator, specifically a four-channel, high-performance, low-jitter clock synthesizer. It is designed to generate 4 independent output clock signals of a wide synthesis range over the range of 496.0 to 992.5 MHz. It can be used to generate clock signals with center frequencies in a very wide range of applications including high-definition graphics cards, RAID systems, hard drives, baseband signal processing, and wireless communications.

The CY25100KZXC46 features spread-spectrum functionality. Spread-spectrum clock signal output helps reduce EMI/EMF levels during high-speed operation, providing improved signal integrity for systems that need to operate with multiple RF frequencies. The clock signal output also has integrated programmable power down and power save modes that allow for lower power consumption when not operating at full speed.

The CY25100KZXC46 is a low jitter clock synthesizer that produces a low jitter, low output clock signal with a maximum integrated cycle-to-cycle jitter of 0.045% of the frequency. This ensures that the clock signal that is produced is extremely accurate, providing clock stability and reliability.

The CY25100KZXC46 works by taking an input frequency, usually a crystal oscillator, and generating 4 output clock signals with the desired frequency range. The clock signal generator utilizes an embedded PLL (phase-locked loop) circuit to synthesize the output frequency, meaning that the desired frequency can be set by a control input or, if desired, changed dynamically.

The CY25100KZXC46 provides complete programmability of the output, including output frequencies, free running/tracking frequency selection, power down/save/wake up modes, voltage, impedance and slew rate, spread-spectrum parameters, and more. The device is packaged in a 9.8mm x 10.0mm QFN56 package and operates over a temperature range of -40 to +85C.

The CY25100KZXC46 clock generator is ideal for applications such as HDTVs and DVRs, HDD and RAID systems, desktop PCs, embedded systems, mobile devices, and more. Additionally, the clock signal generator is compliant to RoHS/REACH, and it is available in both wafer and die form.
