2. PCB Layout Guide
2.1. PCI-e Layout Guide
1. The PCI-e differential pair signals impedance target is 100±20% ohms
impedance.
2. Do not place probe or test points on any high-speed differential signal.
3. Do not route high-speed traces under or near crystals, oscillators, clock signal
generators, switching power regulators, mounting holes, magnetic devices, or ICs
that use or duplicate clock signals.
4. The traces routing don't be 90° angle.
5. For PCI-e add-in card, any layer under edge finger area should be removed.
Including ground and power layers.
6. Ensure that high-speed differential signals are routed at least 1.5 W (calculated
trace-width × 1.5) away from voids in the reference plane. This rule does not apply
where SMD pads on high-speed differential signals are voided.
7. Maximize differential pair-to-pair spacing when possible.
2.2 USB Layout Guide
1. DP/DM traces should always be matched lengths and must be no more than 4
inches in length; otherwise, the eye opening may be degraded.
2. Route DP/DM traces close together for noise rejection on differential signals, parallel
to each other and within two mils in length of each other (start the measurement at
the chip package boundary, not to the balls or pins).
3. A high-speed USB connection is made through a shielded, twisted pair cable with a
differential characteristic impedance of 90 Ω ±15%. In layout, the impedance of DP
and DM should each be 45 Ω ± 10%.
4. DP/DM traces should not have any extra components to maintain signal integrity. For
example, traces cannot be routed to two USB connectors.
5. When a via must be used, increase the clearance size around it to minimize its
capacitance. Each via introduces discontinuities in the signal’s transmission line and
increases the chance of picking up interference from the other layers of the board.
Be careful when designing test points on twisted pair lines; through-hole pins are not
recommended.

Federal Communication Commission Interference Statement:
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
Any changes or modifications not expressly approved by the party responsible for
compliance could void your authority to operate the equipment.
RF exposure statements
This Transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
