Spread Spectrum Frequency Timing Generator

Overview\nThe W155 incorporates the latest advances in PLL-based spread spectrum frequency synthesizer technology. By frequency modulating the SYSCLK output with a low-frequency carrier, peak EMI can be greatly reduced in a system. Use of this technique allows systems to pass increasingly difficult • Generates a spread spectrum timing signal (SYSCLK) and a non-spread signal (USBCLK)\n• Requires a 14.318-MHz crystal for operation\n• Supports MIPS microprocessor clock frequencies\n• Reduces peak EMI by as much as 12 dB\n• Integrated loop filter components\n• Cycle-to-cycle jitter = 250 ps (max)\;
