CM1460: Outstanding EMI Filter Performance With Robust ESD
Protection in Thin Package

California Micro Devices (Nasdaq: CAMD) today introduced a new generation
of its proprietary Praetorian(TM) architecture and products as part of its
ASIP(TM) (Application Specific Integrated Passive(TM)) EMI (electromagnetic
interference) filter portfolio. The Praetorian(TM) CM1460 EMI filter offers
outstanding filter performance combined with a high level of ESD (electrostatic
discharge) protection in an industry leading TDFN (Thin DFN) package. This high
performance single chip solution based on a 3 pole L-C architecture leverages
CMD’s proprietary Praetorian(TM) process technology that allows the integration
of spiral inductors on silicon.

The Praetorian(TM) CM1460 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, 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 (Resistor-Capacitor)
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 CM1460 consists of a 3 pole L-C filter with a minimal
inductor value of 17nH and nominal capacitor values of 15pF. Its 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 CM1460 offers industry leading filter
performance.

In addition, the CM1460 also 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). In order to accommodate various interface
configurations, the CM1460 is available in 4, 6 and 8 channel versions. The
device is housed in an industry leading Thin DFN (TDFN) package featuring a
typical height of 0.75mm and body sizes of 2.00mm x 2.00mm, 3.00mm x 1.35mm
and 4.00mm x 1.60mm for the 4, 6 and 8 channel versions respectively.

Benefits

Using the Praetorian(TM) CM1460, wireless handset designers can benefit
from the highest levels of EMI filtering and ESD protection while still
meeting host processor requirements for input setup time as low as 2ns on the
imager interface. The CM1460 provides EMI filtering and ESD protection in a
single chip 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.

Pricing and Availability

The CM1460 is currently sampling, and pricing starts at $0.34, $0.43 and
$0.52 in 1,000 units for the 4, 6 and 8 channel configurations respectively.
Production is scheduled for Q2 2006. The CM1460 is offered in a lead free TDFN
package.
