Silicon Labs’ precision clocks generate any output frequency from any input frequency while providing jitter attenuation
and clock distribution in high-performance timing applications requiring sub 0.5 ps jitter performance. The devices accept
multiple clock inputs ranging from 2 kHz to 710 MHz and generate multiple low jitter, independent, synchronous clock outputs
ranging from 2 kHz to 945 MHz and select frequencies to 1.4 GHz. The precision clocks are based on Silicon Labs’ proven
third-generation DSPLL^® technology, which generates any output frequency from any input frequency with 300 fs rms jitter
performance in a highly integrated PLL solution that eliminates the need for external VCXO and loop filter components.
JITTER ATTENUATOR FEATURES
• Generates any output frequency from any input frequency
• Ultra-low jitter: 290 fs RMS
• 1-DSPLL and 4-DSPLL versions available
• Integrated loop filter with selectable loop bandwidth
• Hitless switching with phase buildout (auto/manual)
• Freerun or synchronous operating modes
*see page 16 for more about our DSPLLsim software
• Best-in-class PSRR
• I²C/SPI or pin-controlled
• User-selectable output clock signal format
  (LVPECL, LVDS, CML, CMOS)
• Single supply: 1.8, 2.5 or 3.3 V ±10% operation
• Easy-to-use DSPLLsim* configuration software
