CM1484
Dual Channel EMI Filter with ESD Protection
Features
• Two channels of EMI filtering with integrated ESD
protection
• Pi-style EMI filters in a capacitor-resistor-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 20dB attenuation (typical) at 1 GHz
• 5-lead SC70 package
• Lead-free version available
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.
• Wireless handsets
• Handheld PCs/PDAs
• LCD and camera modules
Product Description
The CM1484 is a 2 channel pi-style EMI filter array with
ESD protection, housed in a 5-lead SC-70 package.
The CM1484 has component values of 11pF-100Ω-
11pF per channel. The CM1484 has a cut-off fre-
quency of 220MHz and can be used in applications
with data rates up to 80Mbps. 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.
These devices are particularly well-suited for portable
electronics (e.g. wireless handsets, PDAs, notebook
computers) because of their small package and easy-
to-use pin assignments. In particular, the CM1484 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 CM1484 is housed in a small, 5-lead SC70 pack-
age and is available with lead-free finishing
.
