Ultra Low Capacitance 4 - Line ESD Protection Array VER 1.1 4 Schematic & Pin Configuration As Figure Shown is an example of how to route the high speed differential traces through the ACE00581A.The solid line represents the PCB trace. 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. This is true for lines connected at pins2, 4, and 5 also. Ground is connected at pins3 and 8. One large ground pad should be used in lieu of two separate pads. Application Information (Design Recommendations for HDMI Protection) Adding external ESD protection to HDMI ports can be challenging. First, ESD protection devices have an inherent junction capacitance. However, adding even a small amount of capacitance will cause the impedance of the differential pair to drop. Second, large packages and land pattern requirements cause discontinuities that adversely affect signal integrity. The ACE00581A is specifically designed for protection of high-speed interfaces such as HDMI. They present <0.35pF capacitance between the pairs while being rated to handle +/ -8KV ESD contact discharges (15KVair discharge) as outlined in IEC61000- 4-2. Each device is in a leadless DFN package that is less than 1.1mm wide. They are designed such that the traces flow straight through the device. The narrow package and flow -through design reduces discontinuities and minimizes impact on signal integrity. This becomes even more critical as signal speed increased.
