Description: | 2-Channel Headset/Speaker EMI Filter Array with ESD Protection |
Manufacturer: | ON Semiconductor |
Datasheet: | PDF (208K). Click here to download *) |
The CM1411 is a dual, low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while providing ESD protection. This part is custom-designed to interface with a speaker port on a cellular telephone or similar device. Each high quality filter provides more than 35dB attenuation in the 800 to 2700 MHz range. These pistyle filters support bidirectional filtering that control EMI both to and from a speaker element. They also support AC signals with a cutoff frequency of 31MHz, enabling audio signals to pass through without distortion. |
