SY89529L

The SY89529L is a high-speed, precision PLL-based LVPECL clock synthesizer with spread-spectrum modulation control. With an external 16.66MHz crystal providing a reference frequency to the internal PLL, the differential PECL output frequency will be 200MHz with < 30ps (20ps typ.) peak-to-peak, cycle-to-cycle output jitter. The SY89529L spread-spectrum mode operates with a 30kHz triangle modulation with 0.5% down-spread (+0.0%/ 0.5%). When spread-spectrum is activated, the output signal of SY89529L is modulated which spreads the peak amplitudes and, thus, decreases EMI (Electro-Magnetic Interference).
