Scope

This application note provides detailed information on schematic/layout design, and references RF performance benchmarks. Refer to Type 2EA Datasheet for module specification.

Module Introduction
Type 2EA is a small and high-performance module based on Infineon CYW55573 combo chipset which supports IEEE 802.11a/b/g/n/ac/ax 2×2 MIMO + Bluetooth 5.3 up to 1.2 Gbps PHY data rate on Wi-Fi and 3 Mbps PHY data rate on Bluetooth.
The WLAN section supports PCIe 3.0 Gen2 interface, with optional support for SDIO 3.0. The Bluetooth section supports high-speed 4-wire UART interface and PCM for audio data.
The CYW55573 implements sophisticated enhanced collaborative coexistence hardware mechanisms and algorithms, which ensure that WLAN and Bluetooth is optimized for maximum performance.
In IEEE 802.11ax mode, the WLAN operation supports rates of MCS0 – MCS11 in 20 MHz and 40 MHz and 80 MHz channels for data rate up to 1.2 Gbps.

Features

  • WLAN 802.11a/b/g/n/ac/ax 2×2 MIMO + Bluetooth Classic and Low Energy (Version 5.3) combo SMD module with Infineon CYW55573
  • Small size LGA package with resin molding and metal shielding.
  • Host interfaces: PCIe 3.0 Gen2 and SDIO 3.0 for WLAN; HCI UART, PCM, and I2S for Bluetooth.
  • WLAN MAC address and BD address are stored in OTP

Hardware Block Diagrams
This section shows the difference between the shared-antenna configuration and the dedicated-antenna configuration modules. The key difference is shown in Figure 2. The dedicated-antenna configuration has a dedicated Bluetooth antenna “ANT2”. WLAN has its dedicated antenna “ANT0”. By comparison, the shared-antenna configuration has a single shared WLAN-Bluetooth antenna” ANT0”.

Requirement for High-Speed Digital Signals

  • SDIO: SDIO traces should be isometric zero delay routing with 50 Ω impedance.
  • Pull-ups in the 10 kΩ to 100 kΩ range are required on the four DATA lines and the CMD line. This requirement must be met during all operating states either through the use of external pull-up resistors or through proper programming of the SDIO host’s internal pull-ups.
  • PCIe: TxP/N, RxP/N and CLKP/N signals should be differential 100 Ω impedance. DC blockers are necessary on TxP/N and RxP/N (these should be located very close to the transmission point).

Requirements for Unused Signals
If these signals are not used, no pull-up/down is necessary (floating) for all of GPIOs

3.4 Module Footprint Design
Refer to dimensions in the Type 2EA  DatasheetMuRata-LBEE5XV2EA-Wi-Fi-Plus-Bluetooth-Module-01 . The DXF FileMuRata-LBEE5XV2EA-Wi-Fi-Plus-Bluetooth-Module-01  of module footprint is provided  via website.

  •  Users must copy RF trace to u.FL/MHF I connector from the trace layout file provided by Murata in adherence to the guidelines on:
  • Trace width accuracy within +/- 0.25 mm.
  • Stack height between GND layer and RF trace of 230 ~ 240 µm (Exclude inaccuracy of PCB).
  • Passive component location matching Murata design.
  • Necessary “Keep out” area around u.FL/MHF I connector.
