7 / 10 page PACUSB-D1/D2/D3 Rev. 2 | Page 7 of 10 | www.onsemi.com Application Information The PACUSB-D1/D2/D3 provides a complete interface for a single downstream USB port typically found in computers and USB hubs. It integrates the series resistors (R1) and the 15k Ω pull-down resistors (R2) for both USB data lines (D+ and D-) as well as the capacitors to ground for EMI suppression. Zener diodes provide ESD protection up to 15kV contact discharge per the IEC 61000-4-2 standard and protect the USB controller on both data lines. The PACUSB-D1/D2/D3 should be placed on the PCB between the USB controller and the USB connector, as shown on the Connection Diagram, Figure 5. Figure 5. Connection Diagram for PACUSB-D1/D2/D3 Devices To guarantee the best ESD and filtering performance, it is recommended to physically locate the PACUSB- D1/D2/D3 close to the USB connector. Also, the trace lengths between the PACUSB-D1/D2/D3 and the USB controller should be kept as short as possible. |
