General Description

The CYPRESS FS786/787 are Spread Spectrum Clock Generator ICs (SSCG) designed for the purpose of reducing Electro Magnetic Interference (EMI) found in today’s high-speed digital systems.

The FS786/787 SSCG clocks use an Cypress proprietary technology to modulate the input clock frequency, FSOUT by modulating the frequency of the digital clock.

By modulating the reference clock the measured EMI at the fundamental and harmonic frequencies of FSOUT is greatly reduced.
