Industry’s first CMOS Non-PLL multiplier utilizing analog multiplication of
a high frequency fundamental or 3rd overtone crystal input. Our patented
AFM technology can generate up to 800MHz in PECL, LVDS or CMOS
without using a Phase-Locked Loop. This is achieved with practically no
jitter or phase noise deterioration.

Clock Distribution
Micrel’s clock distribution products consist of zero delay buffers, TCXO fanout buffers,
crystal or reference input fan out buffers, and translator buffers. These general purpose buffer
products will reproduce a master clock frequency up to 1GHz with low skew between the
outputs. Our zero delay buffers use a phase locked loop to ensure zero-delay between the
outputs and the master signal.
