CM1452: All-in-One - Unprecedented EMI Filter Performance in
Industry Leading 0.40mm Pitch CSP MILPITAS, Calif., April 4
/PRNewswire-FirstCall/ -- California Micro Devices (NASDAQ:CAMD)
today introduced a new generation Praetorian(TM) CM1452 EMI
(electromagnetic interference) filter that offers outstanding
filter performance combined with a high level of ESD (electrostatic
discharge) protection in an industry leading, compact 0.40mm pitch
Chip Scale Package (CSP). This high performance single chip
solution leverages CMD's proprietary Praetorian(TM) process
technology allowing the integration of spiral inductors on silicon,
and provides significant advantages in filter performance, ESD
protection, form factor and cost when compared to competing R-C
(Resistor- Capacitor) and ceramic based solutions. (Photo:

The Praetorian(TM) CM1452 provides both superior EMI filtering and
ESD protection for interfaces connecting the host processor to the
camera and display modules in wireless handsets. In popular
clamshell and slider phone configurations, such interfaces are
typically routed on a flexible printed circuit board, and as a
result are highly vulnerable to EMI radiation and potential ESD
strikes. In addition, as data rates increase and signal integrity
requirements become stricter, the use of traditional EMI filters
based on R-C architectures results in significant signal
degradation leading to potential application issues such as visible
data corruption on the display. Key Features Each channel of the
CM1452 consists of a 3 pole L-C filter with a minimum inductor
value of 17nH and nominal capacitor values of 15pF. The CM1452's
insertion loss is much lower than R-C filters, typically less than
1dB. With a typical corner frequency of 300MHz, rolloff of
20dB/octave and attenuation greater than 30dB between 800MHz and
3GHz, the CM1452 offers industry leading filter performance. In
addition, the CM1452 features robust ESD protection up to +/- 15kV
contact discharge per IEC61000-4-2 Level 4 specification and +/- 30
kV using the Human Body Model (HBM). The device is housed in an
industry leading 0.40mm pitch Chip Scale Package (CSP) featuring
sizes of 1.67mm x 1.05mm, 2.47mm x 1.05mm and 3.30mm x 1.05mm for
the 4, 6 and 8 channel versions respectively. This represents an
unique opportunity for designers to save up to 45 percent space
versus equivalent 0.50mm pitch CSP or traditional plastic package
solutions such as TDFN. Competing ceramic solutions require the use
of additional diodes for ESD protection, thus increasing cost and
form factor by up to 55 percent. Benefits Using the Praetorian(TM)
CM1452, wireless handset designers can benefit from the highest
levels of EMI filtering and ESD protection in the most compact
footprint while still meeting the key requirement of maintaining
excellent signal integrity on sensitive data lines such as the
imager or display module interfaces. The CM1452 is the most compact
EMI solution available to wireless handset designers, and provides
a complete EMI/ESD single chip solution compared to ceramic filters
that require the use of external discrete ESD protection devices.
The reduced part count optimizes the footprint and lowers the
overall bill of materials. Moreover, 0.40mm pitch CSP products are
twice as robust from a mechanical standpoint (die strength) as the
equivalent solution in 0.50mm pitch CSP. Pricing and Availability
The CM1452 is currently sampling, and pricing starts at $0.24,
$0.33 and $042 in 1,000 units for the 4, 6 and 8 channel
configurations respectively. Production is scheduled for Q2 2006.
The CM1452 is a lead free product and CMD's Optiguard(TM) coating
option is available for increased robustness. About California
