P2042A

Spread Spectrum Selection

The Modulation Selection Table defines 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, pin1).

For example, P2042A is designed for high-resolution, flat panel applications and is able to support an XGA (1024 x 768) flat

panel operating at 65MHz (FIN) clock speed. A spreading selection of CP0=0, CP1=1 and SR0=0 provides a percentage

deviation of ±1.00% from F_IN. This results in the frequency on ModOUT being swept from 65.65 to 64.35MHz at a modulation

rate of 101.54KHz. Refer Modulation Selection Table. The example in the following illustration is a common EMI reduction

method for a notebook LCD panel and has already been implemented by most of the leading OEM and mobile graphic

accelerator manufacturers.
