Trace lengths are suggested values based on Pericom lab measurements (taken with output pre-emphasis enabled on both Channels) to meet SATA loss and jitter specifications.. Actual trace length supported by PIEQX9 SATA ReDriver TM may be more or less than suggested values and depend on board layout, number of connectors used in the SATA signal path, and SATA host and esata connector design.

5 .0 Board Design and Layout Guidance for PIEQX9 SATA ReDriver TM Family. The Trace Width and Clearance The trace length miss-matching shall be less than mils for the + and traces in the same pairs Match the length between the pairs less than inches Use wider trace width, with 00ohm differential impedance, to minimize the loss for long routes More pair-to-pair spacing for minimal crosstalk Target differential Zo of 00ohm ±0% Figure, the trace width and clearance. The PCB Layers Stackup No new PCB technology required. Use FR is fine. Using standard to 8 layers stack-up with 0.0 inch thick PCB. For micro strip lines, using ½ OZ Cu plated is ok. For strip line in plus players, using OZ Cu is better. Page of AN0 0//0 Pericom Semiconductor Corp.

6 Figure. The Stack-up. The Layout Guidance for the Trace Routings Figure. The Layout Guidance for the Trace Routings. The Topology and Layout Guidance for PIEQX9 SATA ReDriver TM Family Use de-coupling capacitors, 0.uf to 0.uf in size of 00, for all the Vdd pins of PIEQX9 family, as close to the Vdd pins as possible, within -mm if feasible. Use dedicated and GND planes for to minimize the jitters coupled between channel trough power sources. The differential traces shall be away from the strong EMI source and devices, such as the single-ended TTL traces and devices, with at least 0mil to 0mil space. No other components shall piggy ride on the differential traces. Locate the PIEQX9 family device as close to the SATA connector as possible, to traces between the the PIEQX9 family and the SATA connector is allowed, but with to is preferred.
