6- and 8-Channel LCD & Camera EMI Filter Arrays with ESD Protection
Obsolete
概览
The CM1450 comprises a family of inductor-capacitor (L-C) based EMI filter arrays with integrated ESD protection in a CSP form factor. The CM1450-06 and CM1450-08 are configured in 6 and 8 channel formats respectively. Each EMI filter channel of the CM1450 is implemented as a 5-pole L-C filter where the component values are 14pF-17nH-14pF-17nF-14pF. The CM1450's roll-off frequency at -10dB attenuation is 400MHz and can be used in applications where the data rates are as high as 160Mbps while providing greater than 35dB over the 800MHz to 2.7GHz frequency range. The parts integrate ESD protection 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 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.
