cy22800 document #: 001-07704 rev. *a page 2 of 10 general description the cy22800 is a multi-function clock generator that supports various applications in consumer and communications markets. the device uses the cypress proprietary pll along with spread spectrum and vcxo technology to make it one of the most versatile clock synthes izers in the marketplace. the cy22800 is a field-programmable synthesizer that can be programmed using an easy-to-use programmer dongle, cy36800, with one of many pre defined configuration files for fast sample generation of prot otype builds. the cy22800 is a reprogrammable device that can be programmed up to 100 times. the latest configurations available for this device are summarized in table 1 . spread spectrum clock generation (sscg) the cy22800 can generate spread spectrum clocks (sscg) to reduce emi found in today?s high-speed digital electronic systems. the device uses proprietary spread spectrum clock (ssc) technology to synthesize and modulate the frequency of the input clock. by modulating the frequency of the clock, the measured emi at the fundamental and harmonic frequencies is greatly reduced. this reduction in radiated energy can significantly reduce the cost of complying with regulatory agency (emc) requirements and improve time to market without degrading syst em performance. the cy22800 uses a preprogrammed configuration of memory arrays to synthesize output frequency and offers eight different spread percentages (refer to table 1 ? code numbers -015 to -022), and an additional option to turn the spread on and off. for the above-mentioned conf igurations, the modulation frequency varies with the reference frequency as follows: vcxo one of the key components of the cy22800 device is the vcxo. the vcxo is used to ?pull? the reference crystal higher or lower in order to lock the system frequency to an external source. this is ideal for applications where the output frequency needs to track along with an external reference frequency that is constantly shifting. a special pullable crystal must be used in order to have adequate vcxo pull range. pullable crystal specifications are included in this data sheet. vcxo profile figure 1 shows an example of what a vcxo profile looks like. the analog voltage input is on the x-axis and the ppm range is on the y-axis. an increase in the vcxo input voltage results in a corresponding increase in the output frequency. this has the effect of moving the ppm fr om a negative to positive offset. figure 1. vcxo profile 1000 mod ref f f = -200 -150 -100 -50 0 50 100 150 200 00.511.522.533.5 vcxo input [v] tuning [ppm] table 1. cy22800 configurations code # code name input freq.
