UM4601/4611/8601/8611 Multi-line ESD/EMI Protection for Color LCD Interfaces UM4601 DFN8 2.0×2.0 UM4611 DFN8 1.7×1.3 UM8601 DFN16 4.0×1.6 UM8611 DFN16 3.3×1.3 General Description The UM4601/UM4611/UM8601/UM8611 is a (L-C) low pass filter array with integrated TVS diodes. It is designed to suppress unwanted EMI signals and provide electrostatic discharge (ESD) protection in portable electronic equipment. This device utilizes solid-state silicon-avalanche technology for superior clamping performance and DC electrical characteristics. They have been optimized for protection of color LCD and camera lines in cellular phones and other portable electronics. The device consists of identical circuits comprised of TVS diodes for ESD protection, and an inductor - capacitor network for EMI filtering. A typical inductor value of 17nH and a capacitor value of 15pF are used to achieve 24dB minimum attenuation from 800MHz to 2.7GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±15kV (air discharge) and ±8kV (contact discharge) per IEC 61000-4-2, level 4. The UM4601 is in a RoHS compliant DFN8 2.0×2.0 package, the UM4611 is in a RoHS compliant DFN8 1.7×1.3 package, the UM8601 is in a RoHS compliant DFN16 4.0×1.6 package and the UM8611 is in a RoHS compliant DFN16 3.3×1.3 package. The leads are finished with lead-free. The small package makes it ideal for use in portable electronics such as cell phones, digital still cameras, and PDAs.

When examining S parameters, S21 is often described as insertion loss. Insertion Loss and S21 will be used interchangeably from here on out. The insertion loss of a circuit with VOUT and VIN would be expressed as IL = S21(dB) = 20log (VOUT/VIN ) The setup for measuring insertion loss in a 50 Ω system is shown in the figure below. It will be analyzed in a 50Ω environment, so the source impedance and load impedance is 50 Ω. The transfer functions then can be analyzed in terms of insertion loss (S21). TRACKING GENERATOR SPECTRUM ANALYZER 50Ω UNION EMI Filter 50Ω vs + VIN Test Conditions: + VOUT Source Impedance = 50Ω Load Impedance = 50Ω Input Power = 0dBm Cut Off Frequency Cut off Frequency is the frequency at which the signal strength is 3.0 dB less than it is Pass Band 3.0 dB of attenuation equates to half the original signal power. The Pass Band is the range of frequencies that are allowed to “pass” through a filter with minimal attenuation. For our purposes it starts from DC and ends at the cut off frequency. Device Connection The UM4601/UM4611/UM8601/UM8611 is comprised of identical circuits consisting of a low pass filter for EMI suppression and dual TVS diodes for ESD protection. The device is in an 8-pin DFN and 16-pin DFN package. Electrical connection is made to all the pins located at the bottom of the device. A center tab serves as the ground connection. The device has a flow through design for easy layout. All path lengths should be kept as short as possible to minimize the effects of parasitic inductance in the board traces. ________________________________________________________________________ http://www.union-ic.com Rev.05 Dec.2014 5/11 UM4601/4611/8601/8611 Ground Connection Recommendation Parasitic inductance (L) present in the board layout will affect the filtering performance of the device. As frequency (f) increases, the effect of the inductance becomes more dominant. This effect is given by Equation 1.
