4 / CLOCK A ND OSCILL ATOR SELEC TOR

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.

Tiny CMOS Clocks

Si512xx TINY CLOCK FEATURES

• Up to three customizable output frequencies from

3 to 200 MHz
