6- and 8-Channel LCD and Camera EMI Filters with ESD Protection

The CM1409 is a family of pi-style EMI filter arrays with ESD protection, which integrates either six or eight filters (C-R-C) in a small form factor, TDFN 0.50 mm pitch package. The CM1409 has component values of 15pF-100 Ω-15pF per channel. The CM1409 has a cut-off frequency of 110 MHz and can be used in applications with data rates up to 44 Mbps. The parts include ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components against electrostatic discharge (ESD). The ESD protected diodes safely dissipate ESD strikes of ±15 kV, which even exceeds 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 ±30 kV.
