5 5 Copyright Pericom Semiconductor 2007 Last Slide PERICOM CONFIDENTIAL INFORMATION What ReDriver can not help to do For Internal use only  Reflection PCB Stub issue VIA Connector By-pass resistor Stub issue on Layout

6 6 Copyright Pericom Semiconductor 2007 Last Slide PERICOM CONFIDENTIAL INFORMATION How to Add by-pass Circuit for ReDriver For Internal use only  By-Pass Layout Not Good Better for co-layout to decrease the Stub

7 7 Copyright Pericom Semiconductor 2007 Last Slide PERICOM CONFIDENTIAL INFORMATION Layout Guide1 For Internal use only  Layout Considerations for Differential Pairs 1.The trace length miss-matching shall be less than 5 mils for the “+” and “–“ traces in the same pairs 2.Use wider trace width, with 100ohm differential impedance, to minimize the loss for long routes 3.Target differential Zo of 100ohm ±20% 4.More pair-to-pair spacing for minimal crosstalk coupling, it is recommended to have >3X gap spacing between differential pairs. 5.It is preferable to route differential lines exclusively on one layer of the board, particularly for the input traces 6.The use of vias should be avoided if possible, if vias must be used, they should be used sparingly and must be placed symmetrically for each side of a given differential pair. 7.Route the differential signals away from other signals and noise sources on the printed circuit board

When external HDD is unplugged, the “HDD unplugged” current is only about 1.1mA. And when external HDD is plugged in, PI3EQX6741Sx can auto-wakeup for normal working. PI3EQX6741Sx For Internal use only  Termination Detect Feature_1 Waveform in the right is measured at single output of PI3EQX6741Sx before AC capacitors. It means there is no termination at Host or Device side.
