Description
The Si5355 is a highly flexible clock generator capable of synthesizing four
completely non-integer related frequencies up to 200 MHz. The device has four
banks of outputs with each bank supporting two CMOS outputs at the same
frequency. Using Silicon Laboratories' patented MultiSynth fractional divider
technology, all outputs are guaranteed to have 0 ppm frequency synthesis error
regardless of configuration, enabling the replacement of multiple clock ICs and
crystal oscillators with a single device. Through a flexible web configuration utility
called ClockBuilder™ (www.silabs.com/ClockBuilder), factory-customized pin-
controlled Si5355 devices are available in two weeks without minimum order
quantity restrictions. The Si5355 supports up to three independent, pin-selectable
device configurations, enabling one device to replace three separate clock ICs.
