Spread Spectrum Clock Generator

The 7151A-50 is a clock generator for EMI (Electromagnetic Interference) reduction. Spectral peaks are attenuated by modulating the system clock frequency. Down or center spread profiles are selectable. Down spread will not exceed the maximum frequency of an unspread clock, and center spread does not change the average operating frequency of the system IDT offers many other clocks for computers and computer peripherals. Consult IDT when you need to remove crystals and oscillators from your board.
