REQUEST SAMPLES AND DOWNLOAD DOCUMENTATION AT: www.silabs.com/clocks

Silicon Labs’ precision clocks generate any output frequency from any input frequency while providing jitter attenuation

and clock distribution in high-performance timing applications requiring sub 0.5 ps jitter performance. The devices accept

multiple clock inputs ranging from 2 kHz to 710 MHz and generate multiple low jitter, independent, synchronous clock outputs

ranging from 2 kHz to 945 MHz and select frequencies to 1.4 GHz. The precision clocks are based on Silicon Labs’ proven

third-generation DSPLL^®technology, which generates any output frequency from any input frequency with 300 fs rms jitter

performance in a highly integrated PLL solution that eliminates the need for external VCXO and loop ﬁlter components.

JITTER ATTENUATOR FEATURES

• Generates any output frequency from any input frequency

• Ultra-low jitter: 290 fs RMS

• Best-in-class PSRR

• I²C/SPI or pin-controlled

• 1-DSPLL and 4-DSPLL versions available

• Integrated loop ﬁlter with selectable loop bandwidth

• Hitless switching with phase buildout (auto/manual)

• Freerun or synchronous operating modes

• User-selectable output clock signal format

(LVPECL, LVDS, CML, CMOS)

• Single supply: 1.8, 2.5 or 3.3 V 10% operation

• Easy-to-use DSPLLsim* conﬁguration software

Synchronous Ethernet Clock

REQUEST SAMPLES AND DOWNLOAD DOCUMENTATION AT: www.silabs.com/synce

SyncE is used to distribute accurate timing in GbE, 10 GbE, 40 GbE and 100 GbE Carrier Ethernet systems. Every Carrier

Ethernet switch/router requires a high-performance SyncE clock to distribute timing and provide a low jitter Ethernet PHY

reference clock. The Si5328 is the industry’s lowest jitter, fully compliant SyncE clock, making it ideal for Ethernet PHYs

from GbE to 100 GbE. Operating from a single 2.5 or 3.3 V supply, the Si5328 is ideal for providing clock multiplication,

wander ﬁltering and jitter attenuation, in high-performance Synchronous Ethernet-enabled switches and routers.

SYNCE CLOCK FEATURES

• Fully compliant with SyncE clock requirements (ITU G.8262)

• Generates any output frequency (8 kHz to 808 MHz) from

any input frequency (8 kHz to 710 MHz)

• Integrated loop ﬁlter with selectable loop bandwidths:

0.1 Hz; 1 to 10 Hz

• Compact factor 6 mm x 6 mm QFN

• Dual clock outputs with 0.3 ps RMS jitter and any signal

format (LVDS, LVPECL, CML, CMOS)

• Reprogrammable to any frequency without BOM changes

Silicon Labs’ crystal oscillators and voltage controlled crystal oscillators (XO/VCXOs) leverage advanced DSPLL^®circuitry to provide

a low jitter clock at any frequency from 100 kHz to 1.4 GHz. Unlike a traditional XO, where a different crystal is required for each

output frequency, Silicon Labs’ XO/VCXOs use one ﬁxed frequency crystal to provide a wide range of output frequencies. This

IC-based approach allows the crystal resonator to provide exceptional frequency stability and reliability, while providing best-in-

class jitter performance and supply noise rejection, simplifying the task of generating low jitter clocks in noisy environments. All

devices are factory conﬁgurable for a wide variety of user speciﬁcations including frequency, supply voltage, output format and

stability, thereby eliminating long lead times associated with custom oscillators.

Silicon Labs offers complete tools to help designers throughout the entire development process. Both clock and

oscillator solutions offer hardware and software platforms to easily set up, configure and evaluate overall device

performance.

Custom Clock Generator Conﬁgurator

The ClockBuilder Desktop software allows you to configure a

custom clock and generate the NVM file the factory needs in order

to manufacture the custom part.

Configuration and control of Silicon Labs clock generators is mainly

handled through the I²C/SMBus interface. The device also provides

the option of storing a user-definable clock configuration in its

non-volatile memory (NVM), which becomes the default clock

configuration at power-up. Changes to the default configuration

can always be made through the I²C interface.
