General Description

IMI SG521/22/24/28 products are Spread Spectrum Clock Generators designed to reduce the high levels of

Electromagnetic Interference (EMI) found in high-speed digital systems.

By using a modulated clock as the source for all system clocks and timing signals, the amount of radiated energy

(EMI) throughout the system is greatly reduced. Energy reduction is related to the harmonic frequency, such that

the higher the frequency the greater the energy reduction. The 5^thharmonic has greater energy reduction than the

fundamental frequency.

The SG521/2/4/8 products produce a wide range of clock frequencies from 10 to 120 MHz, which are frequency

modulated (PRCLK) by using a Spread Spectrum Clock (SSC) technique to reduce electromagnetic interference

(EMI). In addition, a non-modulated clock output (MPCLK) with various standard clock frequencies is also provided

for the part of the system that could be sensitive to a modulated clock. Refer to the Product Selection and

Frequency Selection Truth Tables for the available modulated and non-modulated clock frequencies.

The spread function can be turned on or off using the SSON control line. When spread is enabled, the modulated

output clock is down-spread at either 1.00% or 3.00% total spread.

These products are designed to be used with fixed frequency external clocks or crystal oscillators. The output clock

frequencies are designed using a 14.318, 44.24 or 48 MHz reference clock.

The products operate from a 3 to 5 volt power supply and 0 to 70°C temperature range. The SG521/2/4/8 parts are

available in 16-pin plastic SOIC packages and in die form.
