AUSTIN, Texas--(BUSINESS WIRE)--March 24, 2008--Silicon
Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today announced the expansion of
its broad portfolio of reconfigurable, frequency-agile precision
clocks to include a single input, single output jitter-attenuating
clock multiplier IC. The new Si5319 Any-Rate Precision Clock is
capable of generating any output frequency from either a crystal or
reference clock input with 0.3 picoseconds jitter generation. The
device supports a free-run mode of operation, enabling the device to
be used as a frequency flexible, low jitter clock generator when
supplied a crystal input. The Si5319 is ideal for providing clock
synthesis, clock multiplication and jitter attenuation in high
performance timing applications such as SONET/SDH/OTN line cards, WDM
line cards, wireless basestations, synchronous Ethernet routers, test
and measurement equipment and broadcast video.
The Si5319 is based on Silicon Labs' patented, third generation
DSPLL® technology, which provides any-rate frequency synthesis and
jitter attenuation in a highly integrated phase-locked loop (PLL)
solution that eliminates the need for external voltage-controlled
crystal oscillator (VCXO) and loop filter components. The Si5319
provides superior frequency flexibility compared to competing IC and
quartz-crystal based devices given its ability to accept any frequency
from 2 kHz to 710 MHz and generate any frequency from 2 kHz to 945 MHz
and select frequencies to 1.4 GHz.
The Si5319 provides a highly integrated, cost-effective jitter
attenuation solution for next-generation multi-rate line cards that
must support a broad array of client-side and line-side interfaces,
including SONET/SDH, 1G/10G Ethernet, Fiber Channel, OTN and HD-SDI.
The timing architecture is dramatically simplified because a single
Si5319 can generate all required reference frequencies with extremely
low jitter, eliminating the need for multiple high frequency VCXOs.
The Si5319 free-run mode of operation greatly simplifies clock
startup issues in high performance applications. In these systems,
customers typically use a high frequency crystal oscillator (XO) to
generate an initial reference clock for the transceiver driving the
high speed fiber optic link. After initial startup, the system
requires a reference clock that is synchronized to another clock in
the system not available at startup. Traditional approaches require
external multiplexer (mux) circuitry to switch between the high
frequency XO and the long-term reference clock. The Si5319 solves this
problem by locking to an inexpensive crystal input at startup and
switching to an active input clock when available. No external mux
components are required and the clock switchover is seamless,
minimizing output clock phase transients that would otherwise generate
bit-errors in the high speed fiber optic interface.
"With the addition of the Si5319, Silicon Labs continues to expand
the industry's broadest portfolio of high performance clock and
oscillator products," said Dave Bresemann, vice president of Silicon
Labs. "Silicon Labs' ability to leverage its mixed-signal design
expertise to the timing market has revolutionized the way timing
systems are designed, ultimately improving performance and reliability
and reducing system complexity."
Silicon Labs' offers a broad portfolio of highly integrated, high
performance timing solutions for datacom, telecom, wireless, video,
and test and measurement markets. In addition to the Any-Rate
precision clock family, Silicon Labs' Si5xx family of oscillators
(XOs) and voltage-controlled oscillators (VCXOs) offer the industry's
shortest lead times, highest reliability and unmatched performance.
These products use optimized DSPLL® technology to shorten cycle
times while eliminating the need for complex resonator fabrication and
tuning. To simplify product selection, Silicon Labs offers a web-based
utility (www.silabs.com/VCXOPartNumber) that validates and generates
part numbers for single, dual, quad and any-rate frequency devices.
Pricing and Availability
The Si5319 is available now in a 6 x 6 mm, 36-lead QFN package.
The device is available in three speed grades based on maximum output
clock frequency. Pricing for the lowest speed grade device, which
supports a clock output frequency range of 2 kHz to 346 MHz, is $19.32
in quantities of 1K.
