One frequency is used for the standard operating mode of the device, while the other frequencies are available for margin testing, either during product development or in system manufacturing test. Table Frequency Select Output Frequency Frequency 0 Frequency 1 Frequency 2 Frequency 3 When changing the output frequency, the frequency transition is not guaranteed to be smooth. There can be frequency excursions beyond the start frequency and the new frequency. Glitches and runt pulses are possible, and time must be allowed for the PLL to relock. Programming Description The CY2XF34 is a programmable device. Before being used in an application, it must be programmed with the output frequencies and other variables described in a later section. Two different device types are available, each with its own programming flow. They are described in the following sections. Field Programmable CY2XF34F Field programmable devices are shipped unprogrammed and must be programmed before being installed on a printed circuit board PCB . Customers use CyberClocks Online Software to specify the device configuration and generate a JEDEC extension .jed programming file. Programming of samples and prototype quantities is available using a Cypress programmer. Third party vendors manufacture programmers for small to large volume applications. Cypress’s value added distribution partners also provide programming services. Field programmable devices are designated with an “F” in the part number. They are intended for quick prototyping and inventory reduction. The CY2XF34 is One Time Programmable OTP . The software is located at CyberClocks TM Online Software Factory Configured CY2XF34 For customers wanting ready-to-use devices, the CY2XF34 is available with no field programming required. All requests are submitted to the local Cypress Field Application Engineer FAE or sales representative. After the request is processed, you receive a new part number, samples, and datasheet with the programmed values. This part number is used for additional sample requests and production orders. Programming Variables Output Frequencies The CY2XF34 is programmed with up to four independent output frequencies, which are then selected using the FS0 and FS1 pins. The device can synthesize frequencies to a resolution of 1 part per million ppm , but the actual accuracy of the output frequency is limited by the accuracy of the integrated reference crystal. The CY2XF34 has an output frequency range of 50 MHz to 690 MHz, but the range is not continuous. The CY2XF34 cannot generate frequencies in the ranges of 521 MHz to 529 MHz, and 596 MHz to 617 MHz. Industrial Versus Commercial Device Performance Industrial and Commercial devices have different internal crystals. This has a potentially significant impact on performance levels for applications requiring the lowest possible phase noise. CyberClocks Online Software displays expected performance for both options. Phase Noise Versus Jitter Performance In most cases, the device configuration for optimal phase noise performance is different from the device configuration for optimal cycle to cycle or period jitter. CyberClocks Online Software includes algorithms to optimize performance for either parameter.
