MODsel

The IMISG536 is a clock generator that integrates

clocking requirements for Multi-Function Products

or stand alone products such as Printers, Copiers,

CPUclk (MHz)

and Scanners.

In addition, it integrates a

Spectrum Spread technology , a modulation

technique designed specifically for reducing EMI

at the fundamental frequency and at its

harmonics. The EMI attenuation is proportional to

the frequency, therefore achieving greater

reduction at the harmonics where it is more

difficult to pass federal regulations for radiated

emissions (such as FCC, CSPIR, etc.).

BLOCK DIAGRAM

XIN

20 MHz

The IMISG536 operates from a 20 MHz

REF

crystal oscillator across pins 2 and 3, or from an

external clock source. The REF output is a

buffered output of the input signal at XIN. CPUclk

is the modulated output for EMI attenuation. This

clock has optional frequency outputs which can

be selected with CPUsel(0:1).

VIDclk (60 MHz) and SCNclk(40 MHz) are highly

accurate fixed frequencies and therefore are not

modulated.
