This product series has a surge capability of 500 Watts PPP per line for an 8/20µs waveshape and offers ESD protection > 40kv. BIDIRECTIONAL COMMON MODE CONFIGURATION (Figure 1) Ideal for use multimode transceiver I/O lines, the PLCDAxxC-6 Series provides up to six (6) lines of protection in a common mode configuration as depicted in Figure 1. LINE 6 LINE 5 LINE 4 Circuit connectivity is as follows: ✔ Line 1 is connected to Pin 1. ✔ Line 2 is connected to Pin 2. ✔ Line 3 is connected to Pin 3. ✔ Line 4 is connected to Pin 8. ✔ Line 5 is connected to Pin 7. ✔ Line 6 is connected to Pin 6. ✔ Pins 4 and 5 are connected to Ground. LINE 3 LINE 2 LINE 1 1 8 2 7 3 6 4 5 BIDIRECTIONAL COMMON MODE CONFIGURATION (Figure 2) The PLCDAxxC-6 Series also provides video line applications six (6) lines of protection in a common mode configuration as depicted in Figure 2. Circuit connectivity is as follows: ✔ Line 1 (Red) is connected to Pin 1. ✔ Line 2 (Green) is connected to Pin 2. ✔ Line 3 (Blue) is connected to Pin 3. ✔ Line 4 (VSYNC) is connected to Pin 6. ✔ Line 5 (HSYNC) is connected to Pin 7. ✔ Pins 4 and 5 are connected to Ground. Figure 1: Typical Transceiver Protection Circuit CIRCUIT BOARD LAYOUT RECOMMENDATIONS Circuit board layout is critical for Electromagnetic Compatibility (EMC) protection. The following guidelines are recommended: The path length between the TVS device and the protected line should be minimized. ✔ All conductive loops including power and ground loops should be minimized. ✔ LINE 3 (BLUE) The protection device should be placed near the input terminals or connectors, the device will divert the transient current immediately before it can be coupled into the nearby traces. ✔ ✔ LINE 2 (GREEN) 4 3 2 1 GRAPHIC CONTROLLER ✔ LINE 1 (RED) The transient current return path to ground should be kept as short as possible to reduce parasitic inductance. DB-15 CONNECTOR 5 6 7 8 LINE 4 (VSYNC) Ground planes should be used whenever possible. For multilayer PCBs, use ground vias.
