Cypress Semiconductor IMIFS787
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.| Part No. | IMIFS787 |
