Si5310
PRECISION CLOCK MULTIPLIER/REGENERATOR IC
Features
Complete precision clock multiplier and clock regenerator device:
Applications
Description
The Si5310 is a fully integrated low-power clock multiplier and clock
regenerator IC. The clock multiplier generates an output clock that is an
integer multiple of the input clock. The clock regenerator operates
simultaneously, creating a “clean” version of the input clock by using the
clock synthesis phase-locked loop (PLL) to remove unwanted jitter and
square up the input clock’s rising and falling edges. The Si5310 uses
Silicon Laboratories patented DSPLL architecture to achieve superior
jitter performance while eliminating the analog loop filter found in
traditional PLL designs with a digital signal-processing algorithm.
The Si5310 represents a new standard in low jitter, small size, low power,
and ease-of-use for clock devices. It operates from a single 2.5 V supply
over the industrial temperature range (–40 to 85 °C).
Functional Block Diagram
Performs clock multiplication to one
of two frequency ranges:
150–167 MHz or 600–668 MHz
Jitter generation as low as
0.5 psrms for 622 MHz output
Accepts input clock from
9.4–668 MHz
Regenerates a “clean”, jitter-
attenuated version of input clock
DSPLL technology provides
superior jitter performance
