Product Description
The CM1451 is an inductor-capacitor (L-C) based
EMI filter array with integrated ESD protection in
CSP. The CM1450-06 and CM1450-08 are
configured in 6 and 8 channel formats respectively.
Each channel is implemented as a 5-pole L-C filter
with the component values 9.5pF-17nH-9.5pF-17nF-
9.5pF. The CM1451's roll-off frequency at -10dB
attenuation is 500MHz. It can be used in applications
where the data rates are as high as 200Mbps while
providing greater than 35dB attenuation over the
800MHz to 2.7GHz frequency range. The device has
ESD protection diodes on every pin that provide a
very high level of protection for sensitive electronic
components that may be subjected to electrostatic
discharge (ESD). The ESD protection diodes
connected to the filter ports safely dissipate ESD
strikes of •15kV, exceeding the Level 4 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) because
of its small package and easy-to-use pin
assignments. In particular, the CM1451 is ideal for
EMI filtering and protecting data and control lines for
the LCD display and camera interface in wireless
handsets while maintaining the integrity of signals
that have rise/fall times as fast as 2ns.
The CM1451 incorporates OptiGuard™, a coating
that results in improved reliability at assembly. The
CM1451 is available in a space-saving, low-profile
Chip Scale Package with optional lead-free finishing.
