CLOCK AND OSCILLATOR SELECTOR / 5
Any-Frequency, Any-Output CMOS Clocks
Silicon Labs’ highly flexible factory and I²C programmable LVCMOS clock generators can be customized to generate
multiple independent non-integer-related frequencies with equivalent frequency synthesis capability of 8 PLLs, with exact
frequency synthesis (0 ppm error), significantly lower jitter, lower power and smaller size than competing solutions. Factory
customization options are available to minimize EMI, including configurable edge rates, output impedance, output skew
and spread spectrum.
Si5350 FEATURES
• Generates any frequency on any output,
  8 kHz to 160 MHz
• Exact clock synthesis: 0 ppm error
• Similar frequency flexibility as 8 independent PLLs
• Crystal or clock input
• <100 ps pk-pk period jitter
• Glitchless switching between output frequencies
• I²C programmable or pin-controlled
• Excellent PSRR: no discrete components
• Two week sample lead time for any custom clock
• Integrated load capacitors
• Spread spectrum clock generation
 -0.1 to -2.5% down, ±0.1 to ±1.5% center
• User-definable control pins Powerdown,
  Output Enable, Spread Enable, Frequency
