| PRELIMINARY CY2XF32 High Performance CMOS Oscillator with Frequency Margining - Pin Control Features Functional Description The CY2XF32 is a high performance and high frequency Crystal Oscillator (XO). It uses a Cypress proprietary low noise PLL to synthesize the frequency from an integrated crystal. The output frequency can be changed via two select pins, allowing easy frequency margin testing in applications. The CY2XF32 is available as a factory configured device or as a field programmable device.

Power Down Operation PD# 0 1 PLL & Xtal Oscillator Off Active Output Buffer Off On Functional Description The FS0 and FS1 pins select between four different output frequencies, as shown in Table 2. Frequency margining is a common application for this feature. 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 2. Frequency Select FS1 0 0 1 1 FS0 0 1 0 1 Output Frequency Frequency 0 Frequency 1 Frequency 2 Frequency 3 Programming Description The CY2XF32 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 below. Field Programmable CY2XF32F Field programmable devices are shipped unprogrammed and must be programmed before being installed on a printed circuit board (PCB). Customers use CyberClocksTM 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 CY2XF32 is one time programmable (OTP). The software is located at www.cyberclocksonline.com. 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. Pin 1 is programmed to function as either OE (output enable) or PD# (power down, active low). The OE function is used to enable or disable the CLK output very quickly, but it does not reduce core power consumption. The PD# function puts the device into a low power state, but the wake up takes longer because the PLL must reacquire lock. Details are shown in Table 3 and Table 4. Table 3. Output Enable Operation OE 0 1 PLL & Xtal Oscillator Active Active Output Buffer Off On Factory Configured CY2XF32 For ready-to-use devices, the CY2XF32 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, the user receives a new part number, samples, and data sheet with the programmed values. This part number is used for additional sample requests and production orders. Document Number: 001-53147 Rev. *B Page 2 of 8 [+] Feedback PRELIMINARY CY2XF32 Programming Variables Output Frequencies The CY2XF32 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 one part per million (ppm), but the actual accuracy of the output frequency is limited by the accuracy of the integrated reference crystal. 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. Table 5. Device Programming Variables Variable Output Frequency 0 (Power on default) Output Frequency 1 Output Frequency 2 Output Frequency 3 Pin 1 Functionality (OE or PD#) Supply Voltage (2.5V or 3.3V) Temperature Range (Commercial or Industrial) Pin 1: Output Enable or Power Down (OE/PD#) Pin 1 is programmed as either Output Enable (OE) or Power Down (PD#). Supply Voltage A programming option optimizes the CY2XF32 for either 2.5V or 3.3V supply voltage. A device programmed for a particular supply voltage is not guaranteed to meet specifications when operated at the other voltage.
