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 compo- nent values are 15pF-17nH-15pF-17nF-15pF. The CM1450's roll-off frequency at -10dB attenuation is 300MHz and can be used in applications where the data rates are as high as 120Mbps while providing greater than 35dB over the 800MHz to 2.7GHz fre- quency 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 are designed and characterized to safely dissipate ESD strikes of ±15kV, beyond 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 elec- tronics (e.g. wireless handsets, PDAs) because of its small package format and easy-to-use pin assign- ments. In particular, the CM1450 is ideal for EMI filter- ing and protecting data and control lines for the LCD display and camera interface in wireless handsets. The CM1450 incorporates OptiGuard ™ which results in improved reliability at assembly. The CM1450 is avail- able in a space saving, low profile Chip Scale Package with optional lead-free finishing. .
