Si535/536 Differential Crystal Oscillators Meet Ultra-Low Jitter
Requirements of Data Center Switches, Routers and Storage Equipment
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Labs (NASDAQ: SLAB), a leader in high-performance, analog-intensive,
mixed-signal ICs, today introduced a new family of crystal oscillators
(XOs) that provide ultra-low jitter reference timing for 10G, 40G and
100G cloud computing and networking equipment. These new Si535 and Si536
XOs leverage Silicon Labs' proven DSPLL®
technology to provide unparalleled performance, stability and
flexibility for 10/40G data center core/access switches, storage area
networking equipment, security routers, enterprise switches/routers, and
Carrier Ethernet switches and routers.
To support the burgeoning demand for cloud computing-based services,
data center equipment is migrating to higher speed serial data
transmission, often 10G or faster. In parallel, there is a significant
trend to maximize energy efficiency by consolidating switching, storage
and computing resources into fewer components. These trends have given
rise to processors, Ethernet switch ICs and FPGAs with integrated
high-speed serializer-deserializer (SerDes) technology that requires
low-jitter timing references. Silicon Labs' Si535/536 oscillators
provide the ultra-low jitter and ±20 ppm stability required by
state-of-the-art cloud computing and networking infrastructure equipment.
The Si535/536 XOs offer exceptional jitter performance of < 200
femtoseconds (fs) RMS jitter (integrated from 10 kHz to 1 MHz) for
common Ethernet and Fibre Channel reference frequencies. The Si535/536
oscillators support LVDS and LVPECL output formats at 2.5 V and 3.3 V
and offer both ±20 ppm and 31.5 ppm total stability, simplifying
interfacing to a wide variety of processors, switches, PHYs and FPGAs.
When combined with Silicon Labs' Si533xx differential clock buffers, the
Si535/536 XOs provide low-jitter clock generation and distribution for
SoCs requiring multiple high-performance reference clocks.
The Si535/536 oscillators use Silicon Labs' patented DSPLL technology to
provide a low-jitter clock at high-speed differential frequencies.
Unlike a traditional XO in which a different crystal is required for
each output frequency, the Si535/536 XOs use a common fixed-frequency
crystal to provide exceptional stability and reliability and leverage
the DSPLL IC to generate any output frequency. In addition, DSPLL clock
synthesis provides superior supply noise rejection, simplifying the task
of generating low-jitter clocks in noisy environments typically found in
data center and networking systems.
Oscillators based on DSPLL technology can be supplied at any output
frequency without cutting and tuning a unique 3rd overtone (OT) crystal
or surface acoustic wave (SAW) device, as required by competing
low-jitter XOs. Silicon Labs' mixed-signal IC-based approach also
enables simplified factory programming at time of shipment, eliminating
long lead times associated with custom oscillators. Si535/536 XO samples
ship in two weeks, the shortest lead time in the high-performance
frequency control industry.
"Cloud computing switches, routers and storage equipment are moving to
higher speed serial data links, increasing the necessity for
high-performance timing," said Mike Petrowski, vice president and
general manager of Silicon Labs' timing products. "We combine
unparalleled performance, simple device customization and a highly
efficient manufacturing flow to deliver both standard and custom
any-frequency XOs with short, reliable lead times, streamlining product
design cycles and eliminating supply chain headaches."

Samples and production quantities of the Si535/536 low-jitter
oscillators are available now. Product pricing for the Si535/536 XOs in
10,000-unit quantities ranges from $8.24 to $11.35 (USD), depending on
