The ClockWizard software enables you to create the configuration file used to program Cypress's CY274x, CY2941x/CY2942x and CY29430, high-performance clock generators.

CY274x is a 4-PLL High-Performance Clock Generator. CY27410 is the industrial device that can generate up to twelve outputs, with eight outputs configured as differential or single-ended, and four dedicated single-ended outputs. CY27430 is the AEC Q-100 automotive device that can generate up to eight outputs, with four outputs configured as differential or single-ended, and four dedicated single-ended outputs. Both the devices support frequencies up to 700 MHz and have <0.7-ps RMS phase jitter. They also meet the reference clock requirements of PCIe 3.0, 10GbE, SATA 2.0 and USB 3.0.

The CY2941x/CY2942x is a PLL-based High-Performance Programmable Crystal Oscillator solution with flexible output frequency options. It is field or factory-programmable for any output frequency between 15 MHz and 2.1 GHz.

The CY29430 is a PLL-based High-Performance Programmable Clock Synthesizer with flexible output frequency options. It is field or factory programmable for any output frequency between 15 MHz and 2.1 GHz. Four frequencies are independently programmable on the differential output with the frequency select (FS) bits. Additionally, other frequency options can be configured with the I2C interface

The ClockWizard software allows you to modify various internal settings in for you to get the required configuration file for the working of the device. The configuration file generated can be used by the Clock Programmer tool to program the device using I2C if you are evaluating the CY27410 using the CY3679 kit, CY29412 with the CY3676 kit or CY29430 using the CY3677 kit.
