PRELIMINARY DATA SHEET

µP-PROGRAMMABLE PRECISION CLOCK MULTIPLIER

Description

Features

The Si5325 is a low jitter, precision clock multiplier for ꢀ Generates any frequency from 10 to 945 MHz and

applications requiring clock multiplication without jitter

attenuation. The Si5325 accepts dual clock inputs ranging

from 10 to 710 MHz and generates two clock outputs ranging

from 10 to 945 MHz and select frequencies to 1.4 GHz. The

two outputs are divided down separately from a common

source. The device provides virtually any frequency

translation combination across this operating range. The

Si5325 input clock frequency and clock multiplication ratio

are programmable through an I²C or SPI interface. The

Si5325 is based on Silicon Laboratories' 3rd-generation

DSPLL^®technology, which provides any-rate frequency

synthesis in a highly integrated PLL solution that eliminates

the need for external VCXO and loop filter components. The

select frequencies to 1.4 GHz from an input

frequency of 10 to 710 MHz

ꢀ Low jitter clock outputs w/jitter generation as low as

0.6 ps rms (30 kHz–1.3 MHz)

ꢀ Integrated loop filter with selectable loop bandwidth

(150 kHz to 2 MHz)

ꢀ Dual clock inputs w/manual or automatically

controlled hitless switching

ꢀ Dual clock outputs with selectable signal format

(LVPECL, LVDS, CML, CMOS)

ꢀ Support for ITU G.709 and custom FEC ratios

(255/238, 255/237, 255/236)

DSPLL loop bandwidth is digitally programmable, providing ꢀ LOS, FOS alarm outputs

jitter performance optimization at the application level.

ꢀ Digitally-controlled output phase adjust

Operating from a single 1.8, 2.5, or 3.3 V supply, the Si5325

is ideal for providing clock multiplication in high performance

timing applications.

ꢀ I C or SPI programmable

ꢀ On-chip voltage regulator for 1.8, 2.5, or 3.3 V
