4 / CLOCK AND OSCILLATOR SELECTOR
Tiny CMOS Clocks
Silicon Labs’ highly flexible, factory and I2C programmable tiny clock LVCMOS generators can be customized to generate
multiple frequencies with significantly lower jitter, lower power and smaller size than competing solutions. Customization
options are available for frequency selection, output enable control, or minimizing EMI, including customizable spread
percentage, modulation rate, output impedance and rise time/fall time.
Si512xx TINY CLOCK FEATURES
• Up to three customizable output frequencies from
  3 to 200 MHz
• Accepts 8 to 48 MHz crystal or 3 to 166 MHz external
  reference clock
• Low cycle-to-cycle jitter: <150 ps
• Low power: 2.3 mA (typ) at 48 MHz output,
  25 MHz xtal in and VDD = 3.3 V
• Center spread modulation from 0.25 to 1.0%,
  with 0.125% resolution
• Programmable spread modulation rate from 30 - 62 kHz
• Customizable drive strengths (four levels
  for each output)
• Customizable control pins (PD#/OE/SSON#/FS)
• Supply range: 1.8 V for Si51214;
  2.5 to 3.3 V for other devices
