CM1452

• 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
• OptiGuard™ Coating for improved reliability at assembly
• RoHS-compliant, lead-free finishing

The CM1452 family of pi-style EMI filter arrays with ESD protection, integrates four, six and eight filters (CL-C) in CSP form factor with 0.40mm pitch. Each EMI filter channel of the CM1452 is implemented as a 3pole 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 is ideal for EMI filtering and protecting data and control lines for the LCD display and camera interface in mobile handsets. because of its small package format and easy-to-use pin assignments.

The CM1452 incorporates OptiGuard™ 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.
