ICS7151

Spread Spectrum Clock Generator

Description

Features

The ICS7151-10, -20, -40, and -50 are clock

generators for EMI (Electro Magnetic Interference)

reduction (see below for frequency ranges and

multiplier ratios). Spectral peaks can be attenuated by

slightly modulating the oscillation frequency. Both down

and center spread profiles are selectable. Down spread

maintains an average frequency less than an unspread

clock, and will not exceed the maximum frequency of

an unspread clock.

• Operating voltage of 3.3 V 0.3 V

• Packaged in 8-pin SOIC

• Available in Pb (lead) free package

• Input frequency range of 16.5 to 33.4 MHz

• Output frequency ranges of 8.3 to 16.7 MHz, 16.5 to

33.4 MHz, 33.3 to 66.7 MHz, 66.6 to 133.4 MHz

• Provides a spread spectrum clock output ( 0.5%,

1.5% center spread; -1.0%, -3.0% down spread)

• Multiplication rates of x1/2, x1, x2, and x4

• Advanced, low-power CMOS process
