Description
The Si5334 is a high performance, low jitter clock generator capable of
synthesizing any frequency on each of the device's four differential output
clocks. The device accepts an external reference clock or crystal and generates
four differential clock outputs, each of which is independently configurable to
any frequency up to 350 MHz and select frequencies to 710 MHz. Using Silicon
Labs' patented MultiSynth technology, each output clock is generated with very
low jitter and zero ppm frequency error. To provide additional design flexibility,
each output clock is independently configurable to support any signal format and
reference voltage. The Si5334 provides low jitter frequency synthesis with
outstanding frequency flexibility in a space-saving 4 x 4 mm QFN package. The
device configuration is factory or field programmed and, upon power up, the
device will begin operation in the predefined configuration without user
intervention. The device supports operation from a 1.8, 2.5, or 3.3 V core supply.
