The CM1690 is a family of pi-style EMI filter arrays with ESD protection from CMD. The product integrates four, six and eight filters (C-L-C) in small form factor uDFN 0.40mm pitch packages. Each EMI filter channel of the CM1690 is implemented as a 3-pole L-C filter where the component values are 16pF-12nH-16pF. The CM1690's roll-off frequency at –6dB attenuation is 330MHz and can be used in applications where the data rates are as high as 140Mbps while providing greater than –35dB attenuation.
The California Micro Devices CM1690 is a family of pi-style EMI filter arrays that integrate four, six, or eight filters (C-L-C) in small form factor uDFN packages. Each channel functions as a 3-pole L-C filter with component values of 16pF-12nH-16pF, designed for high-speed data lines such as LCD and camera interfaces in mobile handsets.
The device features integrated ESD protection diodes on every pin to safeguard sensitive electronic components. It provides greater than -35dB attenuation at 1GHz with a roll-off frequency of 330MHz. The CM1690 is available in ultra-low profile packages with lead-free finishing, compliant with JEDEC standard MO-229C.
