Spread Spectrum Clock Generator
Description
The ICS7152-01, -02, -11, and -12 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. Center
spread maintains an average frequency equal to an
unspread clock. Down spread meets maximum
frequency specs over the entire modualtion cycle.
Features
Operating voltage of 3.3 V ±0.3 V
Packaged in 8-pin SOIC
Input frequency range of 16.6 to 134.0 MHz
Output frequency range of 16.6 to 134.0 MHz
Provides a spread spectrum clock output (±0.5%,
±1.5% center spread; -1.0%, -3.0% down spread)
Advanced, low-power CMOS process
Industrial temperature range available
Available in Pb (lead) free package
