FS781 Datasheet (Cypress Semiconductor) - (FS781 - FS784) Low EMI Spectrum Spread Clock

FS781, (FS781 - FS784) Low EMI Spectrum Spread Clock

The Cypress FS781/82/84 are Spread Spectrum clock generator ICs (SSCG) designed for the purpose of reducing electromagnetic interference (EMI) found in today’s high-speed digital systems.

The FS781/82/84 SSCG clocks use a Cypress-proprietary technology to modulate the input clock frequency, XIN, by

FS781 Features

* Spread Spectrum clock generator (SSCG) with 1×, 2×, and 4× outputs

* 6- to 82-MHz operating frequency range

* Modulates external clocks including crystals, crystal oscillators, or ceramic resonators

* Programmable modulation with simple R-C external loop filter (LF)
