WPEB-265AXI(BT) [XXX] Series Hardware User Manual Introduction This document provides customers with considerations for the hardware design of WPEB-265AXI(BT) [XXX] series. It includes hardware block diagram, reference design, PCB layout, and PCB stack up, which will be explained in detail below. 1.1. Module Block Diagram Figure1. WPEB-265AXI(BT) [XXX] Series PCI-e Half-Mini Card Block Diagram In Figure 1, The WPEB-265AXI(BT) [XXX] series PCI-e Half-Mini Card is a dual-band Wi-Fi 2x2 IEEE 802.11ax module with integrated Bluetooth 5.0. The WLAN host interface is PCI-e v3.0 compliant and runs at Gen2 speeds. The Bluetooth host interface is a USB interface and it also supports UART interface. The WPEB-265AXI(BT) [XXX] is powered by the VDD (3.0V to 3.6V) supplies. All other voltages are provided by internal regulators. &AP12275_ P B 33 AmpakSparkLAN USB(PB33/B18) UART(PR33/PR18) PCIe VDD Antenna2 Antenna1 AP12275_P Series PCI-e Half-Mini Card BT Wi-Fi HOST GPIOs VDD: Typ. 3.3V (3.0V~3.6V)/1.25A WPEB-265AXI(BT) [ B 33 ] GPIOs Voltage Level 18: Typ. 1.8V (1.62V~1.98V) 33: Typ. 3.3V (3.0V~3.6V) B: Bluetooth USB Interface R: Bluetooth UART Interface P: Wi-Fi PCI-e Interface Wireless Module 1.2.

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 …
