This document describes key hardware aspects of the Laird Connectivity Sona™ IF573 series wireless modules providing either PCIe v3.0 Gen2 or SDIO 3.0 interface for WLAN connection and high-speed 4-wire UART interface for Bluetooth[®] connection. This document is intended to assist device manufacturers and related parties with the integration of this radio into their host devices. Data in this document is drawn from several sources and includes information found in the Infineon CYW55573MIWBGT data sheet issued on March 23, 2023, along with other documents provided by Infineon. 

**Note:   The information in this document is subject to change.** Please contact Laird Connectivity to obtain the most recent version of this document. 

The Sona IF573 series wireless module is an integrated, small form factor Wi-Fi/Bluetooth module that is optimized for lowpower mobile devices, featuring: 

- Wi-Fi 6E: Tri-band 2x2 MIMO IEEE 802.11a/b/g/n/ac/ax WLAN 

- Bluetooth[®] 5.4: Dual Mode 

The integration of all WLAN and Bluetooth functionality in a single package supports low cost and simple implementation along with flexibility for platform-specific customization. It is available in both M.2 2230 E-Key and M.2 1318 solder-down form factor. 

This device is pre-calibrated and integrates the complete transmit/receive RF paths including bandpass filter, diplexer, switches, reference crystal oscillator, and power management units (PMU). Both variants support three integrated MHF4 connectors, with two ports for WLAN and one dedicated for Bluetooth. The M.2 1318 solder down module also supports an RF trace pin option for use with external antenna solutions.  For a list of certified antennas see Certified Antennas in the datasheet. 

The Sona IF573 series device supports IEEE 802.11ax tri-band (2.4/5/6 GHz) 2x2 MIMO with data rates up to MCS11 (287 Mbps PHY data rate for 2.4 GHz band and 1.2 Gbps PHY data rate for 5/6 GHz). The device has a dedicated Bluetooth port for best Wi-Fi + Bluetooth coexistence performance. The device’s low power consumption, radio architecture and power management unit (PMU) proprietary power save technologies allow for extended battery life. 

In addition, its tri-band IEEE 802.11ax and Bluetooth radio includes full digital MAC and baseband engines that handle all 802.11 CCK/OFDM/OFDMA® 2.4/5/6 GHz and Bluetooth 5.4 (Basic Rate, Enhanced Data Rate, and Bluetooth Low Energy) baseband and protocol processing.

## 10.2 PCI Express Interface 

The Sona IF573 series wireless module supports the PCIe interface, which provides high-performance serial I/O interconnects and is also protocol compliant and electrically compatible with the PCI Express Base Specification v3.0 running at Gen2 speeds. 

Organization of the PCIe core is in logical layers: Transaction Layer, Data Link Layer, and Physical Layer, as shown in Figure 1Figure 7. A configuration or link management block is provided for enumerating the PCIe configuration space and supporting generation and reception of System Management Messages by communicating with PCIe layers. 

Each layer is partitioned into dedicated transmit and receive units that allow point-to-point communication between the host and Sona IF573 device. The transmit side processes outbound packets whereas the receive side processes inbound packets. Packets are formed and generated in the Transaction and Data Link Layer for transmission onto the high-speed links and onto the receiving device. A header is added at the beginning to indicate the packet type and any other optional fields.

## 10.5 PCM Interface Specifications 

The Sona IF573 series wireless module supports a PCM interface. The PCM interface on the Sona IF573 series wireless module can connect to linear PCM codec devices in Master/Slave mode. In Master mode, the Sona IF573 generates the BT_PCM_CLK and BT_PCM_SYNC signals, and in Slave mode, these signals are provided by another master on the PCM interface and are input to the Sona IF573 module. 

The configuration of the PCM interface may be adjusted by the host through the use of vendor-specific HCI commands.

## 10.4 JTAG Interface 

The Sona IF573 supports the JTAG interface for use with proprietary debug and characterization test tools during board bringup. 

**Note:** The JTAG interface is disabled by default and not exposed on the M.2 2230 E-Key interface.

https://www.lairdconnect.com/ 

**Americas** : +1-800-492-2320 **Europe** : +44-1628-858-940 **Hong Kong** : +852-2762-4823 

Sona IF573 has two signals that allow the host to control power consumption by enabling or disabling the Bluetooth, WLAN, and internal regulator block. 

- WL_REG_ON: Used to power up the WLAN. When this pin is high, the internal regulators are enabled and the WLAN section is out of reset. When this pin is low the WLAN section is in reset.  This signal is connected to the W_DISABLE1# pin on the M.2 interface. 

- BT_REG_ON: Used to power up the Bluetooth section. If both the BT_REG_ON and WL_REG_ON pins are low, the regulators are disabled. When this pin is low and WL_REG_ON is high, the Bluetooth section is in reset.  This signal is connected to the W_DISABLE2# pin on the M.2 interface. 

- **M.2 1318** - VBAT and VDDIO should not rise 10% - 90% faster than 40 microseconds. 

- **M.2 1318** - VBAT should be up before or at the same time as VDDIO. VDDIO should NOT be present first or be held high before VBAT is high. 

- Do not access the digital interface for at least 150 milliseconds after VDDC and VDDIO are available.

## 14 HOST PLATFORM IMPLEMENTATION DETAILS 

The Sona IF573 M.2 1318 module must be configured for either PCIe or SDIO WLAN interface.  Configuration is done with resistor strapping as specified in Table 38. 

_**Table 38: Wi-Fi host interface configuration table**_ 

|**_Table 38: Wi-Fi host interface configuration table_**|||||
|---|---|---|---|---|
|**WLAN/Bluetooth Interface**||**GPIO_1 (Pin24)**||**LED_1# (Pin 65)**|
|PCIe / UART|H||H||
|SDIO /UART|L||H||



**Note:** The M.2 2230 E-Key module strapping is implemented on the M.2 carrier board. 

The CYW55573 Bluetooth CPU core requires the UART_CTS input to be held low at the point the BT_REG_ON (W_DISABLE2#) signal goes high to enable secure firmware download.  In addition, the HCI interface uses the standard H4 protocol which requires four-wire hardware handshaking. 

This requires that the host implement GPIO control over BT_REG_ON/W_DISABLE2# and implement full RTS/CTS handshaking. 

The Sona IF573 requires a 32KHz clock on the SUSCLK input.  This clock drives various internal state machines and must be provided by the host even if low power operation is not needed. 

## 13.4 M.2 1318 WL_DEV_WAKE Mapping 

The WL_DEV_WAKE feature is mapped to different pins on the M.2 1318 module depending on the WLAN interface selection. See Table 39 for details. 

_**Table 39: M.2 1318 WL_DEV_WAKE Mapping**_ 

|**WLAN Interface**|**M.2 1318 Pin**|**M.2 1318 Pin**|**M.2 1318 Pin**|**Internal GPIO**|
|---|---|---|---|---|
|PCIe|22|||GPIO_8|
|SDIO|18|||LHL_GPIO1|



**Note:** This feature is subject to software support and not currently implemented.

## 15 RF LAYOUT DESIGN GUIDELINES 

The following is a list of RF layout design guidelines and recommendation when installing a Laird Connectivity radio into your device. 

- Do not run antenna cables directly above or directly below the radio. 

- Do not place any parts or run any high-speed digital lines below the radio. 

- Ensure that there is the maximum allowable spacing separating the antenna connectors on the Laird Connectivity radio from the antenna. In addition, do not place antennas directly above or directly below the radio. 

- Laird Connectivity recommends the use of a double-shielded cable for the connection between the radio and the antenna elements. 

- Be sure to put a 10uF/16V/0603 capacitor on EACH 3.3V power pin. Place the capacitor as close as possible to the pin to ensure correct PMU operation. 

- Use proper electro-static-discharge (ESD) procedures when installing the Laird Connectivity radio module. To avoid negatively impacting Tx power and receiver sensitivity, do not cover the antennas with metallic objects or components.

## 20.1 Overview 

The Sona IF573 Series module is listed on the Bluetooth SIG website as a qualified Controller Subsystem. 

**Design Name Owner Declaration ID Link to listing on the SIG website** ~~a es Rs~~ Sona IF573 Laird D057578 https://launchstudio.bluetooth.com/ListingDetails/158180 Connectivit y 

It is a mandatory requirement of the Bluetooth Special Interest Group (SIG) that every product implementing Bluetooth technology has a Declaration ID. Every Bluetooth design is required to go through the qualification process, even when referencing a Bluetooth Design that already has its own Declaration ID. The Qualification Process requires each company to register as a member of the Bluetooth SIG – www.bluetooth.org 

The following is a link to the Bluetooth Registration page: https://www.bluetooth.org/login/register/ 

For each Bluetooth Design, it is necessary to purchase a Declaration ID. This can be done before starting the new qualification, either through invoicing or credit card payment. The fees for the Declaration ID will depend on your membership status, please refer to the following webpage: 

https://www.bluetooth.org/en-us/test-qualification/qualification-overview/fees 

For a detailed procedure of how to obtain a new Declaration ID for your design, please refer to the following SIG document, (login is required to views this document): 

https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=283698&vId=317486 

## 20.2 Qualification Steps When Referencing a Laird Connectivity 

To qualify your product when referencing a Laird Connectivity Controller Subsystem design, follow these steps: 

1. To start a listing, go to: https://www.bluetooth.org/tpg/QLI_SDoc.cfm 

**Note:** A user name and password are required to access this site. 

2. In step 1, select the option, New Listing and Reference a Qualified Design. 

3. Enter D057578 in the Controller Subsystem table entry. 

4. Enter your complimentary Host Subsystem and optional Profile Subsystem QDID in the table entry. 

5. Select your pre-paid Declaration ID from the drop-down menu or go to the Purchase Declaration ID page. 

**Note:** Unless the Declaration ID is pre-paid or purchased with a credit card, you cannot proceed until the SIG invoice is paid. 

6. Once all the relevant sections of step 1 are finished, complete steps 2, 3, and 4 as described in the help document accessible from the site. 

Your new design will be listed on the SIG website and you can print your Certificate and DoC. 

For further information please refer to the following training material:
