Si51x XO/VCXOs Family Provides Frequency-Flexible Timing Solution for
Cost-Sensitive Applications up to 250 MHz
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Laboratories Inc. (NASDAQ: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today introduced a family of crystal
oscillators (XOs) and voltage-controlled XOs (VCXOs) designed to
minimize jitter, system cost and design complexity for a wide range of
high-performance, cost-sensitive applications up to 250 MHz. The new
Si51x XO/VCXO family provides best-in-class frequency flexibility for
networking, communications, storage, server, embedded computing and
broadcast video systems and also targets FPGA, serializer/deserializer
(SerDes) and multi-rate clocking applications.
The latest addition to Silicon Labs' portfolio of frequency-flexible
crystal oscillators, the Si51x family includes the industry's first
I2C-programmable, low-jitter XOs and the first dual-frequency XO/VCXOs
in space-saving 3.2 mm x 5 mm packages. The Si51x family offers drop-in
compatibility with fixed-frequency XOs and surface acoustic wave (SAW)
oscillators while providing superior frequency flexibility and power
supply noise rejection. Featuring 0.8 picosecond (ps) rms jitter across
the entire frequency range, the Si51x XO/VCXOs provide up to 2.5X lower
jitter than traditional factory-programmable oscillators.
The Si51x XO/VCXOs feature Silicon Labs' patented DSPLL®
technology to generate any frequency from 100 kHz to 250 MHz with 26
parts per trillion frequency programming resolution. Unlike traditional
crystal and SAW oscillators that require a unique crystal or SAW
resonator for each frequency, the Si51x devices pair a DSPLL clock IC
with a single low-frequency crystal. Specific device configurations are
programmed during outgoing tests. This efficient mass-customization
approach minimizes lead times because there is no need to customize
crystals for each new frequency. Silicon Labs can respond quickly to
demand upsides, reducing customer inventory stocking levels and
associated costs. High reliability and quality are maintained because
all Si51x oscillator products share a common manufacturing flow.
Silicon Labs' Si512/3 dual-frequency XOs are ideally suited for
replacing two discrete XOs and a multiplexer in networking, broadcast
video and other applications that use multi-rate SerDes devices and
FPGAs. The Si514 I2C-programmable XO can be used to replace clock
generators that require an external crystal for local clock generation,
simplifying design while providing tighter, guaranteed stability by
leveraging the Si514's internal crystal. The Si514 also can be used to
replace direct digital synthesis (DDS) clock ICs and digital PLLs that
typically use a digital-to-analog converter (DAC) and VCXO for clock
synchronization. The Si514 is a flexible choice for prototyping since it
can be reprogrammed in-system to any frequency.
The Si51x XO/VCXOs support a wide range of voltage options (1.8, 2.5 and
3.3 V) and output formats (LVPECL, LVDS, CMOS and HCSL), making them
ideal for applications that require varying frequencies, formats and
power supply voltages. All Si51x devices include on-chip voltage
regulation, minimizing the impact of system-level power supply noise on
clock jitter and keeping jitter below 1 ps rms jitter even in noisy
system environments. This noise immunity is advantageous in FPGA-based
systems that rely on tightly regulated switched mode power supplies. By
filtering power supply noise inside the device, Si51x XO/VCXOs can be
mounted next to FPGAs without requiring external low drop-out regulators
for power supply filtering.
"Silicon Labs' new Si51x XO/VCXO family delivers an optimal combination
of low jitter performance, frequency agility, high reliability and small
footprint for high-performance clocking applications," said Mike
Petrowski, general manager of Silicon Labs' timing products. "By
combining our efficient manufacturing flow with device customization and
programmability, Silicon Labs can offer any-frequency Si51x XO/VCXOs
with short, reliable lead times, accelerating product design cycles and
simplifying the supply chain."
