capacitor (C-R-C) network
• ±15kV ESD protection on each channel
(IEC 61000-4-2 Level 4, contact discharge)
• ±30kV ESD protection on each channel (HBM)
• Greater than 30dB attenuation (typical) at 1GHz
• 6-lead SOT-563 package
• Available with lead-free finishing
Applications
• LCD and camera data lines in mobile handsets
• I/O port protection for mobile handsets,
notebook computers, PDAs, etc.
• EMI filtering for data ports in cell phones, PDAs
or notebook computers

• Handheld PCs/PDAs
• LCD and camera modules
Product Description
The CM1485 is a 2 channel pi-style EMI filter array
with ESD protection, housed in a 6-lead SOT-563
package. The CM1485 has component values of
12pF-100Ω-12pF per channel. The CM1485 has a
cut-off frequency of 125MHz and can be used in
applications with data rates up to 48Mbps. The
parts include ESD diodes on every pin, which
provide a very high level of protection for sensitive
electronic components that may be subjected to
electrostatic discharge (ESD). The ESD protection
diodes safely dissipate ESD strikes of ±15kV, well
beyond the maximum requirement of the IEC61000-
4-2 international standard. Using the MIL-STD-883
(Method 3015) specification for Human Body Model
(HBM) ESD, the pins are protected for contact
discharges at greater than ±30kV.
This device is particularly well-suited for portable
electronics (e.g. wireless handsets, PDAs,
notebook computers) because of its small package
and easy-to-use pin assignments. In particular, the
CM1485 is ideal for EMI filtering and protecting data
and control lines for the I/O data ports, LCD display
and camera interface in mobile handsets.
The CM1485 is housed in a small, 6-lead SOT-563
package and is available with lead-free finishing.
