MILPITAS, Calif., June 30 /PRNewswire-AsiaNet/ –

CM1430 and CM1431 Bring High Performance EMI Filters and ESD Protection in
0.4mm Pitch TDFN Packages

California Micro Devices (Nasdaq: CAMD) today introduced a new family of
packaged Centurion(TM) ASIP(TM) (Application Specific Integrated Passive(TM))
EMI (electromagnetic interference) filter arrays that feature superior EMI
filtering performance combined with robust ESD (electrostatic discharge)
protection in the most compact package available for use in mobile handsets.
The new Centurion(TM) CM1430 and CM1431 ASIP(TM) devices are packaged in a
0.4mm pitch TDFN package that produces space savings of up to 42 per cent when
compared to existing 0.5mm pitch TDFN packages. With the adoption of higher
resolution color displays and camera imagers spreading to a larger segment of
the handset market, there is a growing need for EMI filters that offer higher
cutoff frequencies while providing a greater level of attenuation performance
at the frequency band of 800 MHz through 3.0GHz. The Centurion(TM) CM1430 and
CM1431 devices are the first packaged EMI filters that meet these exacting
requirements in a form factor fully optimized for use in space constrained,
mobile handset applications.

Key Features
The Centurion(TM) CM1430 and CM1431 utilize C-R-C pi filters with values of
8.5pF-100Ohms-8.5pF and 15pF-100Ohms-15pF respectively corresponding to cutoff
frequencies of 200MHz and 120MHz. Their high cutoff frequencies make these
products ideal for filtering high resolution display and camera modules
interfaces, which utilize data rates up to 80Mbps. The CM1430 and CM1431
achieve attenuation of -25dB and -35dB respectively, at 1GHz. The attenuation
of both parts is -35dB at 3 GHz. Both products feature flow through routing for
each filter channel which contributes to enhanced filter performance and ease
of printed circuit board (PCB) layout. Additionally, superior filter
performance across all channels is achieved through the large area ground pad
on the bottom of the TDFN package that minimizes parasitic inductance. In
addition to filtering, both products also provide ESD protection up to +/-15kV
contact discharge per IEC61000-4-2 Level 4 specification. The Centurion(TM)
CM1430 and CM1431 are both available in 4, 6 and 8 channel configurations.

Smallest EMI Filter Solutions in TDFN Packages
With design trends toward more feature rich, multimedia capable and
smaller, thinner handset designs, board space for components has become
increasingly constrained. To address this, California Micro Devices has worked
closely with our assembly partners to develop a more space efficient, low
profile 0.4mm TDFN package. In the 4 channel version, for example, the
Centurion(TM) CM1430 and CM1431 require 42 per cent less board space than
competing filters using popular 0.5mm pitch TDFN packages. For the 6 channel
and 8 channel versions, space savings of approximately 30 per cent are
achieved. The package dimensions of the 4, 6 and 8 channel versions are:
1.7mm x 1.35mm (8 leads), 2.5mm x 1.35mm (12 leads) and 3.3mm x 1.35mm
(16 leads) respectively. Each of these packages is available in lead free
finish.

Pricing and Availability
Samples of the Centurion(TM) CM1430 and CM1431 are available now. Sample
pricing ranges between $0.42 and $0.59 each in 1,000 unit quantities, depending
on the channel configuration. Production for both families is scheduled for Q3
2005.
