IEC 61000-4-2 (ESD) ±15kV (air), ±10kV (contact) Description IEC 61000-4-5 (Lightning) 3.5A (8/20µs) AZ1045-04F is a design which includes ESD rated diode arrays to protect high speed data interfaces. The AZ1045-04F has been specifically designed to protect sensitive components which are connected to data and transmission lines from over-voltage caused by Electrostatic Discharging (ESD). AZ1045-04F is a unique design which includes ESD rated, ultra low capacitance steering diodes and a unique design of clamping cell which is an equivalent TVS diode in a single package. During transient conditions, the steering diodes direct the transient to either the internal ESD line or to ground line. The internal unique design of clamping cell prevents over-voltage on the internal ESD line and on the I/O line, which is protecting any downstream components. AZ1045-04F may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). For operating voltage of 5V and below

Device Connection The AZ1045-04F is designed to protect four data lines from transient over-voltage (such as ESD stress pulse). The device connection of AZ1045-04F is shown in the Fig. 1. In Fig. 1, the four protected data lines are connected to the ESD protection pins (pin1, pin2, pin4, and pin5) of AZ1045-04F. The ground pins (pin3 and pin8) of AZ1045-04F are the negative reference pins. data line I/O 1 I/O 2 I/O 2 Line-1 Line-2 1 10 NC 2 9 GND 3 Line-3 Line-4 To I/O-port Connector I/O 1 data line 4 AZ1045-04F To I/O-port Connector These pins should be directly connected to the GND rail of PCB (Printed Circuit Board). To get minimum parasitic inductance, the path length should keep as short as possible. AZ1045-04F can provide ESD protection for 4 I/O signal lines simultaneously. If the number of I/O signal lines is less than 4, the unused I/O pins can be simply left as NC pins.

Application AZ1045-04F is designed for protecting high speed I/O ports from over-voltage caused by Electrostatic Discharging (ESD). Thus, a lot of kinds of high speed I/O ports can be the applications of AZ1045-04F, especially, the HDMI port. HDMI Protection for High and Low speed signals The HDMI Compliance Test Specification (CTS) requires sink (receiver) ports maintain a differential impedance of 100 Ohms +/- 15%. ESD protection devices have an inherent junction capacitance. Even a small amount of added capacitance on a HDMI port will cause the impedance of the differential pair to drop. Thus, some form of compensation to the layout will be required to bring the differential pairs back within the required 100 Ohm +/- 15% range. The higher the added capacitance, the more extreme the modifications will need to be. If the added capacitance is too high, compensation may not even be possible. The AZ1045-04F presents 0.5pF capacitance to each differential signal while being rated to handle >8kV ESD contact Revision 2013/03/08 4 ©2013 Amazing Micro. www.amazingIC.com AZ1045-04F Ultra Low Capacitance ESD Protection Array For High Speed I/O Port discharges (>15kV air discharge) as outlined in IEC 61000-4-2. Therefore, it is possible to make none adjustment to the board layout parameters to compensate for the added capacitance of the AZ1045-04F. Figure 2 shows how to implement the AZ1045-04F in a HDMI application. The AZ1045-04F is designed for allowing the traces to run straight through the device to simplify the PCB layout. As shown in Figure 2, the best way to design the PCB trace is using the flow through layout. The solid line represents the PCB trace. Note that the PCB traces are used to connect the pin pairs for each line (pin 1 to pin 10, pin 2 to pin 9, pin 4 to pin 7, pin 5 to pin 6). For example, line 1 enters at pin 1 and exits at Pin 10 and the PCB trace connects pin 1 and 10 together. Lines 2, 3, and 4 have the same way of connection. The ground pins (pin3 and pin8) of AZ1045-04F are the negative reference pins. These pins should be directly connected to the GND plane of PCB. To get minimum parasitic inductance, the path length should keep as short as possible. In Figure 2, the none-TMDS signals, DDC_CLK, DDC_DAT, CE_REMOTE, and HOTPLUG_DET, can be protected with another low cost part, e.g., AZC199-04S.

Measurement Results on a HDMI port Fig. 3a and 3b show the test boards for measuring the differential impedance of a HDMI port without using ESD protection array, and with using AZ1045-04F ESD protection array, respectively. Fig. 4 shows the differential impedance measurement results. The range of the differential impedance without ESD protection array on it is from 96Ω to 106Ω, which meets the spec of 100 Ohms +/- 15%. And the range of the differential impedance with AZ1045-04F ESD protection array on it is from 88.9Ω to 104Ω, which still meets the spec of 100 Ohms +/- 15%. From the measured results shown in Fig. 4, the degradation of the differential impedance induced by the parasitic effects of AZ1045-04F is at the range of 12.8Ω to 14.2Ω. This demonstrates when the PCB differential impedance is designed at around 105Ω, then none adjustment to the board layout parameters is needed to compensate for the added ultra small capacitance of the AZ1045-04F and the test results can pass the spec of 100Ω +/- 15%. Fig. 5 shows the HDMI Eye Diagram performance when the AZ1045-04F is under used. No apparent affection is shown due to the low capacitance feature of the AZ1045-04F.
