ON Semiconductor Introduces Active Spread Spectrum Clock Generator ICs for EMI Reduction in Portable, Consumer and Computing Applications
PHOENIX --(Business Wire)--
ON (News - Alert) Semiconductor (Nasdaq: ONNN),
a premier supplier of high performance silicon solutions for energy
efficient electronics, has introduced a new series of active
spread spectrum clock generator integrated circuits (ICs) that
manage electromagnetic interference (EMI) and Radio Frequency
Interference (RFI (News - Alert)) at the clock source, delivering system-wide EMI
reduction of all clock dependent signals.
The P3P8203A
LVCMOS peak EMI reduction clock generator targets applications such
as graphics cards, computing and consumer applications. This device
supports an input voltage of 3.3 V, a frequency range of 18 MHz to 36
MHz, and analog control of spread spectrum deviation by means of an
external resistor. By choosing a different value of the external
resistor to provide the desired amount of spread spectrum deviation at
the output, system designers now have the added flexibility to customize
their applications to achieve the desired EMI reduction. The P3P8203A is
housed in an 8-pin, 2 mm x 2 mm x 0.8 mm WDFN package, making it ideal
for use in PCB space constrained applications. Operating temperature
range is 0�C to +70�C.
The P3MS650100H
and P3MS650103H
LVCMOS peak EMI reduction clock generators are ideal for use in PCB
space constrained applications such as portable, battery powered devices
- including mobile phones and tablets where EMI/RFI can be a
significant challenge and compliance with regulations is a prerequisite.
Housed in a miniature four-pin WDFN package measuring 1 mm x 1.2 mm x
0.8 mm, these versatile new devices are spread spectrum clock generators
that provide the industry's smallest standalone active solution for
reducing EMI/RFI at the clock source as well as downstream clock and
data signals derived from the clock source. The P3MS650100H and
P3MS650103H support input voltages ranging from 1.8 volts (V) to 3.3 V,
typical spread spectrum deviations of 0.45 percent to 1.4 percent, and
reduction of EMI/RFI in clock sources with a frequency range of 15
megahertz (MHz) to 60 MHz. Operating temperature range is -20�C to +85�C.
"The need to achieve EMI regulatory compliance while controlling costs
and minimizing PCB real estate is a significant challenge for mobile and
computing applications," said Ryan Cameron, vice president of Industrial
and Timing Products at ON Semiconductor. "Our new EMI reduction ICs
address these challenges on all fronts by providing a cost-effective
solution that reduces EMI/RFI at the source and at all downstream clock
and data signals derived from the source. By implementing these devices
early in the design cycle, design engineers potentially avoid the need
for alternate solutions and the inclusion of costly additional PCB
layers or shielding to deal with EMI/RFI problems."
Packaging and Pricing
The P3P8203A is offered in an eight-pin WDFN package and is priced at
$0.44 per unit in 10,000 unit quantities. The P3MS650100H and
P3MS650103H are offered in a four-pin WDFN package and are priced at
$0.24 per unit in 10,000 unit quantities.
