RClamp0524PA RClamp0522P 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 RClamp0524PA 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 RRRRRCCCCClllllaaaaammmmmppppp00000555552222244444PPPPPAAAAA Figure 1 is an example of how to route the high speed differential traces through the RClamp0524PA. 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 100 Ohms ±15% without any PCB board modification. Figure 3 shows a typical impedance test result for a TDR risetime of 200ps using a Semtech evaluation board with 100 Ohm traces throughout. Measure- ments were taken using a TDR method as outlined in the HDMI Compliance Test Specification (CTS). In each © 2011 Semtech Corp. 6 www.semtech.com

RClamp0524PA RClamp0522P PROTECTION PRODUCTS PRELIMINARY Applications Information case, the device meets the HDMI CTS requirement of 100 Ohm ±15% with plenty of margin. Figure 3 shows a typical HDMI 1.3 eye pattern at 1080p resolution. As shown there are no violations of the eye pattern with RClamp0524PA in the circuit. The RClamp0524PA may also be used to protect the remaining lines (I2C, CEC, and hot plug). Figure 4 shows the complete protection solution. 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 following guidelines are recommended: (cid:122) Place the device as close to the connector as pos- sible. This practice restricts ESD coupling into adjacent traces and reduces parasitic inductance. X-axis 1.79 (nsec) (cid:122) The ESD transient return path to ground should be Y-axis 98.3 (Ohm) kept as short as possible. Whenever possible, use multiple micro vias connected directly from the device Figure 2 - TDR Measurement with 200ps risetime ground pad to the ground plane. using Semtech Evaluation Board (cid:122) Avoid running critical signals near board edges. Note: Measurements were taken on SLP HDMI EVAL Rev C Board that has 100Ω differential traces impedance throughout (No trace Compensation). Protecting MDDI Ports with RClamp0524PA and RClamp0522P The small package size and low capacitance of the RClamp0522P and RClamp0524PA 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 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 RClamp0524PA 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. Devices on the main board are needed to protect the MDDI controller in the Baseband processor and devices on the LCD board to protect MDDI controller in LCD module. A single line TVS such as the Figure 3 - Typical HDMI 1.3 Eye Pattern (1080p) uClamp0501P is used to protect the MDDI power line. with RClamp0524PA The protection devices should be placed close to the connector of each board. Traces are routed directly through each device, minimizing parasitic inductance. Connections to the ground plane should be made with multiple micro vias when possible. © 2011 Semtech Corp. 7 www.semtech.com
