cy22800 document number: 001-07704 rev. *e page 4 of 18 spread spectrum clock generation (sscg) the cy22800 can gener ate 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 system performance. the cy22800 uses a preprogramm ed configuration of memory arrays to synthesize output frequency and offers eight different spread percentages (refer to the cy22800 configurations on page 5 ? 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 t he 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 2 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 from a negative to positive offset. figure 2. 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] [+] feedback
