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 is modulated which spreads the peak amplitudes
and, thus, decreases EMI (Electro-Magnetic Interference).
