Spread Spectrum Selection
Table 1 illustrates the possible spread spectrum options. The optimal setting should minimize system EMI to the
fullest without affecting system performance. The spreading is described as a percentage deviation of the center
frequency (Note: the center frequency is the frequency of the external reference input on CLKIN, Pin 1).

Example: P2160 is designed for high-resolution flat panel applications and is able to support UXGA (1600 X
1200) flat panel that operates on 162 MHz (Fin) clock speed. A spreading selection of FS0=1, SR0=1 and
modulation rate selection MRA=1, enables input frequency range from 80 ~ 166 MHz and provides a
percentage deviation of +/-1.00% (see Table 1) of the input frequency (Fin). This results in frequency on
ModOUT being swept from 160.38 MHz to 163.62 MHz at a modulation rate of 42.18 KHz (162 MHz/80 MHz X
20.83KHz). This particular example (see below figure) given here is a common EMI reduction method for
notebook and LCD monitor manufacturers and has already been implemented by most of the leading OEM and
mobile graphic accelerator manufacturers.
