EMI9106

EMI9106 EMI Filter for MicroSD Interfaces Description The EMI9106 is a combination EMI filter and line termination device with integrated TVS diodes for use on Multimedia Card interfaces. This state−of−the−art device utilizes solid−state, silicon− avalanche technology for superior clamping performance and DC electrical characteristics. The EMI9106 has been optimized for protection of MicroSD interfaces in cellular phones and other portable electronics. The EMI9106 consists of six circuits that includes series impedance matching resistors as required by the SD specification. TVS diodes are included on each line for ESD protection. An additional TVS diode connection is included for protection of the voltage (Vcc) bus. Termination resistor value of 40 W is provided on the SDData0, SDData1, SDData2, SDData3, CMD, and CLK lines. The TVS diodes provide effective suppression of ESD voltages in excess of ±15 kV (contact discharge) per IEC 61000−4−2, level 4. The EMI9106 is in a 16−pin, RoHS/WEEE compliant, UDFN 16−pin package. It measures 3.30 x 1.35 x 0.50 mm. The leads are spaced at a pitch of 0.4 mm and are finished with lead−free NiPd. Features Bidirectional EMI/RFI Filtering and Line Termination with Integrated ESD Protection Provides ESD Protection to IEC61000−4−2: ±15 kV Contact Discharge TVS Working Voltage: 3.3 V Termination Resistors: 40 W Typical Capacitance per Line: 12 pF (VIN = 2.5 V) Protection and Termination for Six Lines + Vcc Solid−state Technology Ap...
