The output frequencies requested will be matched as closely as the internal PLL divider and multiplier options allow. All custom requests must be submitted to your local Cypress FAE or sales representative. The method to use to request custom configurations is: Use CyClocks software. This software automatically calculates the output frequencies that can be generated by the CY229x devices and provides a print-out of final pinout which can be submitted in electronic or print format to your local FAE or sales representative. The CyClocks software is available free of charge from the Cypress website or from your local sales representative. Once the custom request has been processed you will receive a part number with a 3-digit extension e.g., CY2292SC-128 specific to the frequencies and pinout of your device. This will be the part number used for samples requests and production orders.
