PR Newswire (US)
Offers Superior EMI Filtering for High Speed Data Interfaces with
Cost Reduced Architecture MILPITAS, Calif., June 30
/PRNewswire-FirstCall/ -- California Micro Devices (NASDAQ:CAMD)
today announced its third generation Praetorian III LC filter
architecture for mobile handsets. Setting a new benchmark for
filter performance, Praetorian III products offer higher
performance than Praetorian I products, at lower cost equivalent to
the recently introduced Praetorian II family of products. Based on
an innovative coupled inductor design, CMD's Praetorian III
architecture features filters with higher levels of inductance and
lower levels of capacitance. This results in filter designs that
offer greater levels of attenuation together with superior signal
integrity compared to competing products. Growth of High Bandwidth
Data Interfaces Products based on the Praetorian III architecture
address the most challenging EMI filter and ESD protection
requirements found in today's advanced handset designs including
high resolution color LCD displays, camera imagers and removable
memory interfaces. "Increased consumer demand for feature phones
and smart phones is expected to drive handset volume growth in the
coming years," commented Tina Teng, analyst, wireless
communications for iSuppli Corporation. "iSuppli forecasts unit
volume growth for these combined categories to achieve a compound
annual growth rate of 9.3% from 2008 through 2011 versus 6.0% for
the entire handset market. Products that address the application
needs of high resolution displays and imager and high density
removable memory stand to benefit from the expected increase in
demand." Praetorian III Architecture The Praetorian III
architecture utilizes a six pole pi-filter topology and features
high cutoff frequencies, high levels of attenuation and robust ESD
protection up to 15kV contact discharge consistent with the IEC
61000-4-2 level 2 standard. Taking advantage of higher value
inductors in the available chip area, it allows the use of smaller
value capacitors resulting in a filter design with input
capacitance as low as 10pF, significantly enhancing signal
integrity. The coupled inductor's compact size also allows the
design of filters that can fit into small form factor 0.4mm pitch
uDFN and chip scale packages (CSP). "With the growth in high
bandwidth data applications, finding a filtering solution with low
channel capacitance has become an important concern to handset
design engineers worried about maintaining signal integrity,"
stated Kyle Baker, CMD's vice president of marketing. "Praetorian
III products offer an ideal solution for these applications,
offering industry leading performance at new, lower price points,"
he continued. New products based upon the Praetorian III
architecture will sample in the third quarter. About California
