cy2x014 document number: 001-10179 rev. *h page 5 of 15 programming description the cy2x014 is a programmable device. prior to being used in an application, it must be prog rammed with the output frequency and other variables described in programming variables . two different device types are available, each with its own programming flow. they are described in the following sections. field-programmable cy2x014 field programmable devices are shipped unprogrammed and must be programmed before being installed on a printed circuit board (pcb). customers use cyclockwizard? software to specify the device configur ation and generate a jedec (extension .jed) programming file. programming of samples and prototype quantities is available using the cyclockwizard software along with a cy3675-clkmaker1 cyclockmaker clock programmer kit with a cy3675-lcc6a socket adapter . 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 software and programmer kit hardware can be downloaded from www.cypress.com by clicking the hyperlinks in the previous paragraph. factory-configured cy2x014 for ready-to-use devices, the cy2x 014 is available with no field programming required. pre-configured devices (see standard and application-specific factory configurations ) are available for samples or orders, or a requ est for a custom configuration can be made. 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 datasheet with the programmed values. this part number is used for additional sample requests and production orders. the cy2x014 is one-time programmable (otp). programming variables output frequency the cy2x014 can synthesize a frequency 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. the cy2x014 has an output frequency range of 50 mhz to 690 mhz, but the range is not continuous. the cy2x014 cannot generate frequencies in the ranges of 521 mhz to 529 mhz and 596 mhz to 617 mhz. pin 1: output enable (oe) or power down (pd#) pin 1 is programmed as either oe or pd#. the oe function is used to enable or disable the clk output 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 the lock. industrial versus commerc ial device performance industrial and commercial devices have different internal crystals. they have a potentia lly significant impact on performance levels for applicatio ns requiring the lowest-possible phase noise. cyclockwizard software allows the user to select between and view the expected performance of both options. table 1. device programming variables variable output frequency pin 1 function (oe or pd#) temperature range (commercial or industrial)
