ICS7151 - Spread Spectrum Clock Generator

Description

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.

Features

  • 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 ±1.5% center spread; -1.0%, -3.0% down spread).
  • Provides a spread spectrum clock output (±0.5%,.
  • Multiplication rates of x1/2, x1, x2, and x4.
  • Advanced, low-power CMOS process Block Diagra.

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.
