New Si5350/51 Any-Frequency Octal Clock Generators with On-Chip VCXO
Provide Programmable Solution for Cost-Sensitive Consumer Market
MUNICH--(BUSINESS WIRE)--
Silicon
Laboratories Inc. (NASDAQ: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today introduced the industry's most
frequency flexible in-circuit programmable CMOS clock generators. The
new Si5350/51 octal clock generators with on-chip voltage-controlled
crystal oscillators (VCXOs) replace traditional multi-component
phase-locked loop (PLL) solutions with a single clock IC that delivers
twice the frequency flexibility, 70 percent lower jitter and 30 percent
lower power than competing timing products. The Si5350/51 clocks are
optimized for cost-sensitive consumer electronics products such as DVRs,
HDTVs, set-top boxes and gaming systems as well as printers, projectors,
video conferencing, blade servers, single-board computers, RAID systems,
femtocells and telecom customer premises equipment.
The Si5350/51 clock generators leverage Silicon Labs' patented
MultiSynth technology to provide superior frequency flexibility, lower
jitter, lower power and smaller footprint than any three-PLL or four-PLL
clock generator on the market today. Unlike traditional clock generators
that require a separate PLL to synthesize each non-integer related
output frequency, the Si5350/51 devices synthesize a unique frequency on
each of their eight output clocks. By integrating clock synthesis in the
clock device's output divider stage rather than its PLL, the Si5350/51
provides the equivalent clock synthesis capability of eight PLLs while
dramatically reducing board space and power consumption.
The Si5350/51 generates all system clocks (audio, video, interface and
SoC) and can synthesize any combination of eight unique,
non-integer-related frequencies up to 133 MHz with 0 ppm frequency
error. The Si5350/51 can also simultaneously generate free-running
clocks from a crystal input as well as clocks synchronized to a
reference clock or analog control voltage input, allowing multiple
board-level timing domains to be clocked from a single device.
"Silicon Labs innovative timing technology has enabled customers to save
time and cost in high-end enterprise and communications applications,
eliminating supply chain headaches and providing an unparalleled level
of design flexibility," said Mike Petrowski, general manager of Silicon
Labs' timing products. "With the introduction of our Si5350/51 clocks,
we are bringing our timing technology to bear on cost-sensitive consumer
applications to provide reduced system cost, power and space
requirements without sacrificing performance."
The Si5350/51 clocks simplify system-level design by providing
glitchless frequency shifting between two rates on up to six of the
device outputs. This frequency shifting technique simplifies clock
synthesis in audio and video applications, which often require a
combination of frequencies to support multiple formats and display
standards. It also eases processor overclocking to improve CPU
performance in embedded applications and enables board-level power
savings by enabling a dynamic reduction in output clock frequency.
Custom factory-programmed pin-controlled versions of the Si5350 clock
generator are available using Silicon Labs' web-based ClockBuilder™
utility. The ClockBuilder configuration utility provides turnkey,
application-specific clocks, eliminating the need for field programming
hardware and software. Since the Si5350/51 does not require metal mask
changes to customize clock frequencies like traditional clock ICs, lead
times are reduced from six weeks to less than two weeks for custom
clocks. Silicon Labs also offers a field programming kit to enable rapid
prototyping of both the Si5350 and Si5351 clocks.
Pricing and Availability
Samples of the Si5350/51 clock generators are available in space-saving
4x4 mm 20-QFN, 24-QSOP and 10-MSOP packages. Production quantities are
planned to be available at the end of 4Q10 for all Si5350/51 products.
Pricing ranges from $0.66 (3 outputs) to $2.38 (8 outputs) in
10,000-unit quantities. The Si535x-20QFN-EVB and Si535x-24QSOP-EVB
evaluation boards are available now and priced at $150. (All prices USD.)
