CY2XF33 High-Performance LVDS Oscillator With Frequency Margining – Pin Control Features Functional Description ■ Low jitter crystal oscillator (XO) ■ Less than 1 ps typical RMS phase jitter ■ Differential LVDS output ■ Output frequency from 50 MHz to 690 MHz The CY2XF33 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 through two select pins, allowing easy frequency margin testing in applications. ■ Two frequency margining control pins (FS0, FS1) ■ Factory configured or field programmable ■ Integrated phase-locked loop (PLL) ■ Supply voltage: 3.3 V or 2.5 V ■ Pb-free package: 5.0 × 3.2 mm LCC ■ Commercial and industrial temperature ranges The CY2XF33 is available as a factory configured device or as a field programmable device.

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 FS0 0 0 Frequency 0 Output Frequency 0 1 Frequency 1 1 0 Frequency 2 1 1 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 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 CY2XF33 is one time programmable (OTP). The software is located at CyberClocks(TM) Online Software. Factory Configured CY2XF33 For customers wanting ready-to-use devices, the CY2XF33 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. The CY2XF33 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.5 Document Number: 001-53148 Rev. *E Page 3 of 12 CY2XF33 Application-Specific Factory Configurations Part Number VDD CY2XF33LXC700T 3.3 V FS1 FS0 Output Frequency RMS Phase Jitter (Random) Offset Range Jitter (Typical) 12 kHz to 20 MHz 0.65 ps 0 0 100.00 MHz 0 1 125.00 MHz 0.61 ps 1 0 200.00 MHz 0.55 ps 1 1 250.00 MHz 0.53 ps Programming Variables Output Frequencies The CY2XF33 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 CY2XF33 has an output frequency range of 50 MHz to 690 MHz, but the range is not continuous. The CY2XF33 cannot generate frequencies in the ranges of 521 MHz to 529 MHz and 596 MHz to 617 MHz. Table 3. Device Programming Variables Variable Output frequency 0 (Power on default) Output frequency 1 Output frequency 2 Output frequency 3 Optimization (phase noise or jitter) Temperature range (Commercial or industrial) 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.
