RClamp0524J PROTECTION PRODUCTS PRELIMINARY Applications Information 8 7 GND 6 5 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 1 2 GND 3 4 and land pattern requirements cause discontinuities that adversely affect signal integrity. The RClamp0524J is specifically designed for protection of Pin Identification high-speed interfaces such as HDMI. They present <0.3pF capacitance between the pairs while being 1,2,3,4 Input Lines rated to handle >±8kV ESD contact discharges (>±15kV air discharge) as outlined in IEC 61000-4-2. Output Lines 5,6,7,8 (NoInternal Connection) Each device is in a leadless SLP package that is less than 1.1mm wide. They are designed such that the GND Ground traces flow straight through the device. The narrow package and flow-through design reduces discontinuities and minimizes impact on signal integrity. SLP2710P8 Pin Configuration (Top View) This becomes even more critical as signal speeds increase. Pin Configuration Figure 1 is an example of how to route the high speed differential traces through the RClamp0524J. The solid line represents the PCB trace. The PCB traces are used to connect the pin pairs for each line (pin 1 to pin 8, pin 2 to pin 7, pin 3 to pin 6, pin 4 to pin 5). For 1 1122 example, line 1 enters at pin 1 and exits at Pin 8 and 1111 the PCB trace connects pin 1 and 8 together. This is 1100 true for lines connected at pins 2, 3, and 4 also. GND GND rr Ground is connected at the center tabs. One large oo 99 tt ground pad should be used in lieu of two separate cc 88 ee nn 77 pads. nn oo 1 CC TDR Measurements for HDMI I I 66 MM 55 The combination of low capacitance, small package, and DD 44 HH flow-through design means it is possible to use these GND GND devices to meet the HDMI impedance requirements of 33 100 Ohm ±15% without any PCB board modification. 22 11 Figures 3 and 4 show impedance test results for a TDR risetime of 200ps and 100ps respectively, using a Semtech evaluation board with 100 Ohm traces through- FFFFFiiiiiggggguuuuurrrrreeeee 11111.....

RClamp0524J PROTECTION PRODUCTS PRELIMINARY Applications Information requirement of 100 Ohm ±15% with plenty of margin. For signal integrity purposes, the best results will be obtained by using the RClamp0524J to protect the high-speed differential pairs. This is because the BB device is designed such that the data lines from the connector line up with the I/O pins of the device without altering the trace routing. Either the RClamp0504P or RClamp0524J may be used to AA protect the remaining lines (I2C, CEC, and hot plug) depending on layout constraints. Layout Guidelines for Optimum ESD Protection Good circuit board layout is critical not only for signal integrity, but also for effective suppression of ESD in- duced transients. For optimum ESD protection, the A B following guidelines are recommended: X-axis 1.905 2.081 (nsec) (cid:122) Place the device as close to the connector as pos- Y-axis 101.0 107.0 (Ohm) sible. This practice restricts ESD coupling into adjacent traces and reduces parasitic inductance. Figure 2 - TDR Measurement with 200ps risetime (cid:122) The ESD transient return path to ground should be using Semtech Evaluation Board kept as short as possible. Whenever possible, use multiple micro vias connected directly from the device ground pad to the ground plane. (cid:122) Avoid running critical signals near board edges.
