Si5315 Dramatically Simplifies Frequency Conversion
AUSTIN, Texas--(BUSINESS WIRE)--Dec. 17, 2008--Silicon
Laboratories Inc. (NASDAQ:SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today introduced the expansion of
its Any-Rate Precision Clock family with the Si5315, a
jitter-attenuating clock multiplier IC that meets or exceeds the
performance, integration, frequency and jitter requirements for the 1G
and 10G Synchronous Ethernet (SyncE) market. The Si5315 is the
industry's only SyncE clock multiplier IC to support 10G line encoding
rates (161.13 MHz) in addition to SONET/SDH and Ethernet frequencies.
The device requires no external phase-locked loop (PLL) components,
dramatically simplifying line card design and frequency translation in
carrier Ethernet switch routers (CESR), wireless backhaul, 3G/4G base
stations, multi-service access platforms, passive optical networking, IP
DSLAM and T1/E1 infrastructure.
As service providers upgrade legacy circuit switched networks to more
cost-effective carrier Ethernet/IP networks, communications equipment
suppliers face challenges when translating between legacy SONET/SDH and
Ethernet clock frequencies. Existing SyncE clock ICs and
voltage-controlled crystal oscillator-based module level solutions are
limited by a combination of poor jitter performance, limited frequency
flexibility and lack of integration, which ultimately make these
traditional solutions difficult to use.
The Si5315 provides the lowest jitter of any SyncE clock IC in the
industry at less than 0.6 ps rms phase jitter, meeting the jitter
requirements specified by ITU-T G.8262 and providing significant margin
to Gigabit Ethernet (GbE) and 10 GbE PHY jitter requirements. The Si5315
achieves this level of performance by leveraging Silicon Labs' patented
DSPLL® technology to integrate all key components of a high-performance
analog PLL on chip, thereby providing excellent immunity to system noise
sources. For ease of use, the Si5315 generates more than 200 of the most
popular frequency translations required in SyncE line card applications,
simplifying design and reducing BOM cost and complexity.
"Current SyncE solutions are incomplete because they do not provide the
breadth of frequencies and jitter performance to fully meet 10G
requirements," said Dave Bresemann, vice president of Silicon Labs.
"Silicon Labs' solution provides an unprecedented level of frequency
flexibility, integration and performance, simplifying design and
lowering costs for our customers."
In addition to this new family of SyncE clocks, Silicon Labs offers an
expansive portfolio of frequency flexible, low jitter any-rate clock
generators and buffers, jitter attenuating clock multipliers, XO/VCXOs,
and silicon oscillators. These products use optimized DSPLL® and
MultiSynth technology to shorten lead times and deliver outstanding
jitter performance for datacom, telecom, wireless, broadcast video, test
and measurement, and consumer markets.
Pricing and Availability
The Si5315 is packaged in a space-saving 36-lead, 6x6 mm QFN package
with samples available in January and full production in Q1 2009. The
Si5315A for 10G applications is priced at $17.72 in 1,000 piece
quantities. The Si5315B for 1G applications is priced at $12.50 in 1,000
piece quantities.
