NOTICE - The following device(s) are recommended alternatives:

The 7151-10, -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.

Features

  • Operating voltage of 3.3 V ±0.3 V
  • Packaged in 8-pin SOIC
  • Pb (lead) free package, RoHS compliant
  • 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
