RClamp0522P RClamp0524P PROTECTION PRODUCTS PRELIMINARY Applications 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. Furthermore, adding even a small amount of capacitance will cause the 1 1122 impedance of the differential pair to drop. Second, 1111 large packages and land pattern requirements cause 1100 discontinuities that adversely affect signal integrity. GND GND The RClamp0524P and RClamp0522P are specifically oror 99 tt designed for protection of high-speed interfaces such cc 88 ee as HDMI. They present <0.4pF capacitance between nn 77 nn the pairs while being rated to handle >±8kV ESD oo 1 CC contact discharges (>±15kV air discharge) as outlined 66 II MM 55 in IEC 61000-4-2. Each device is in a leadless SLP DD 44 package that is less than 1.1mm wide. They are HH GND GND designed such that the traces flow straight through the 33 device. The narrow package and flow-through design 22 reduces discontinuities and minimizes impact on signal 11 integrity. This becomes even more critical as signal speeds increase. FFFFFiiiiiggggguuuuurrrrreeeee 11111..... FFFFFlllllooooowwwww ttttthhhhhrrrrrooooouuuuuggggghhhhh LLLLLaaaaayyyyyooooouuuuuttttt UUUUUsssssiiiiinnnnnggggg Pin Configuration RRRRRCCCCClllllaaaaammmmmppppp00000555552222244444PPPPP Figure 1 is an example of how to route the high speed differential traces through the RClamp0524P. 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 pins 2, 4, and 5 also. Ground is connected at pins 3 and 8. One large ground pad should be used in lieu of two separate pads. The same layout rules apply for the RClamp0522P. TDR Measurements for HDMI The combination of low capacitance, small package, and flow-through design means it is possible to use these devices to meet the HDMI impedance requirements of 100Ohm ±15% without any PCB board modification. 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 throughout. Measurements were taken using a TDR method as outlined in the HDMI Compliance Test © 2008 Semtech Corp. 6 www.semtech.com

RClamp0522P RClamp0524P PROTECTION PRODUCTS PRELIMINARY Applications Information Specification (CTS). In each case, the device meets the HDMI CTS requirement of 100 Ohm ±15% with plenty of margin. For signal integrity purposes, the best results will be BB obtained by using the RClamp0524P to protect the high-speed differential pairs. This is because the device is designed such that the data lines from the connector line up with the I/O pins of the device AA without altering the trace routing. The RClamp0504P may be used to protect the remaining lines (I2C, CEC, and hot plug). 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- A B duced transients. For optimum ESD protection, the X-axis 1.905 2.081 (nsec) following guidelines are recommended: Y-axis 101.0 107.0 (Ohm) (cid:122) Place the device as close to the connector as pos- sible. This practice restricts ESD coupling into Figure 2 - TDR Measurement with 200ps risetime adjacent traces and reduces parasitic inductance. using Semtech Evaluation Board (cid:122) The ESD transient return path to ground should be 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. Protecting MDDI Ports with RClamp0524P and RClamp0522P The small package size and low capacitance of the BB RClamp0522P and RClamp0524P make them ideal for high-speed lines in portable applications. One such application is the protection of MDDI ports in cellular phones. MDDI is a serial data interface operating at AA 480Mb/s per line pair. The lines are scalable for increased speed and display resolution. A MDDI port protection example is shown in Figure 5. The RClamp0524P is used to protect two differential line pairs while an RClamp0522P is used to protect the MDDI strobe lines. Note that devices are used on both the main board and LCD side of the MDDI port. A B Devices on the main board are needed to protect the X-axis 1.80 2.076 (nsec) MDDI controller in the Baseband processor and Y-axis 96 108.0 (Ohm) devices on the LCD board to protect MDDI controller in LCD module. A single line TVS such as the uClamp0501P is used to protect the MDDI power line. Figure 3 - TDR Measurement with 100ps risetime The protection devices should be placed close to the using Semtech Evaluation Board connector of each board. Traces are routed directly through each device, minimizing parasitic inductance. Note: Measurements were taken on SLP HDMI EVAL Rev C Board that has 100Ω Connections to the ground plane should be made with differential traces impedance throughout (No trace Compensation). multiple micro vias when possible. © 2008 Semtech Corp. 7 www.semtech.com
