with ESD Protection
CM1452
Features
• Four, six and eight channels of EMI filtering with
integrated ESD protection
• ±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 1 GHz
• Chip Scale Package (CSP) with 0.40mm pitch
and 0.25mm CSP solder ball which features
extremely low parasitic inductance for optimum
filter and ESD performance
• OptiGuardTM Coating for improved reliability at
assembly
• RoHS-compliant, 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.
• Wireless handsets
• Handheld PCs/PDAs
• LCD and camera modules
Product Description
The CM1452 family of pi-style EMI filter arrays with
ESD protection, integrates four, six and eight filters
(C-L-C) in CSP form factor with 0.40mm pitch. Each
EMI filter channel of the CM1452 is implemented as a
3-pole L-C filter where the component values are
20pF-17nH-20pF. The CM1452 roll-off frequency at -
6dB attenuation is 330MHz and can be used in
applications where the data rates are as high as
132Mbps and provide greater than 30dB over the
800MHz to 2.7GHz frequency range. The ESD
diodes on every I/O pin provide a very high level of
ESD protection for sensitive electronic components.
The ESD protection diodes connected to the filter
ports are designed and characterized to safely
dissipate ESD strikes of ±15kV, 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.
The CM1452 incorporates OptiGuardTM which results
in improved reliability at assembly. The CM1452 is
manufactured with a 0.40mm pitch and 0.25mm CSP
solder ball to provide up to 28% board space savings
vs. competing CSP devices with 0.50mm pitch and
0.30mm CSP solder ball.

Note 1: All parameters specified at TA = –40°C to +85°C unless otherwise noted.
Note 2: ESD applied to input/output pins with respect to GND, one at a time. Clamping voltage is measured at the opposite side
of the EMI filter to the ESD pin (i.e. if ESD is applied to pin A1 then clamping voltage is measured at pin C1).
Note 3: Unused pins are left open.
