Cypress Semiconductor Corp. Integrated Circuits (ICs) - Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers IMISM560BZ

The IMISM560BZ is a Spread Spectrum Clock Generator IC designed to reduce electromagnetic interference (EMI) in high-speed digital electronic systems. It operates within a frequency range of 25 to 108 MHz and features low power dissipation, consuming 85 mW at 50 MHz. The device supports both clock and crystal inputs and includes a frequency spread disable function, allowing for flexible modulation options. This IC utilizes a proprietary Phase-Locked Loop (PLL) and Spread Spectrum Clock (SSC) technology to synthesize and modulate the input frequency, significantly lowering EMI levels by 8 to 16 dB. The modulation profile is symmetrically centered on the input frequency, and the frequency and spread percentage can be selected using tri-level logic inputs (S0 and S1), providing nine different settings. The IMISM560BZ is packaged in an eight-pin SOIC format and is suitable for applications such as VGA controllers, LCD panels, and printers. It operates within a temperature range of 0 to 70¬8C, making it a versatile choice for various electronic projects.
