cy2907 document number: 38-07137 rev. *g page 4 of 13 functional description the cy2907 is a general purpose clock generator designed for use in a wide variety of applications?from graphics to pc peripherals to disk drives. it generates selectable system clock frequencies from a single referenc e input (crystal or reference clock). the cy2907 is configured with an eprom array, similar to the other devices in th e cypress eprom programmable clock family, making it easy to customize for any application. furthermore, the cy2907 is compatible with all industry standard 9107 and 9108 clock synthesizers. device programming two versions of the cy2907 are available - field programmable and factory programmable. field programmable devices must be programmed before being installed in an application. they are one-time-programmable (otp). customers can program small quantities in-house using the cypress cy3670 programmer. production quantities are available through cypress?s value-added distribution partners, or by using third party programmers from bp microsystems, hi-lo systems, and others. for high volume orders, devices can be factory programmed by cypress. all requests must be 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 a data sheet with the programmed values. this part number is used for additional sample requests and production orders. cyberclocks? software cyberclocks is an easy-to-use software application that enables the user to configure any one of the eprom programmable clocks offered by cypress. you may specify the input frequency, pll and output frequencies, and different functional options. note the output frequency rang es in this data sheet when specifying them in cyberclocks to make sure that you stay within the limits. after a configuration is established, you can print the configuration and save programming files in ent and jed formats. cyberclocks runs on pcs running the windows ? operating system, and is available for free download on the cypress semiconductor website at www.cypress.com . within the cyberclocks application, the cy2907 is found in the cyclocks ? section. note that the standalone cyberclocks software should not be confus ed with the cy berclocks online software, which is a web-based application that is used to configure other programmable clock devices. cypress cy3670 programming kit cypress?s cy3670 is a portable programmer that connects to a pc serial port and enables users of cyclocks software to quickly and easily program any of the cy2291f, cy2292f, cy2071af, and cy2907f devices. an adapter is also required and is ordered separately. the CY3097 is the adapter for the cy2907f8. for the cy2907f14, order adapter cy3098. maximum ratings exceeding maximum ratings may shorten the useful life of the device. user guidelines are not tested. supply voltage ................................................. ?0.5 to +7.0 v input voltage ........................................ ?0.5 v to v dd + 0.5 v storage temperature (non-condensing).... ?65 c to +150 c max soldering temperature (10 sec)........................ +260 c junction temperature............................................... +150 c static discharge voltage........................................... > 2000 v (per mil-std-883, method 3015) operating conditions [3] parameter description min max unit v dd supply voltage, 5 v operation 4.5 5.5 v supply voltage, 3.3 v operation 3.0 3.6 v t a commercial operating temperature, ambient 0 70 c c l maximum capacitive load ? 15 pf f ref external reference crystal 10.0 25.0 mhz external reference clock [4, 5] 1.0 30.0 mhz notes 3. electrical parameters are guar anteed with these operating conditions. 4. guaranteed by design, not 100% tested in production. 5. load = max typical configuration, f ref = 14.318 mhz. specific configurati ons may vary. a close approximation of i dd can be derived by the following formula: i dd (ma) = v dd (6.25 + (0.055 f ref ) + (0.0017 c load (f clka + refclk))). c load is specified in pf and f is specified in mhz.
