WLAN FUNCTIONAL DESCRIPTION
Overview
The M2US50NBT/M2SD50NBT WLAN block is based on the Laird SSD50NBT SIP (System in Package). It is
optimized for low-power embedded applications and is configured to operate in dual-band, two-stream (2x2
MIMO) mode. Its functionality includes:
Improved throughput on the link due to frame aggregation, RIFS (reduced inter-frame spacing), and half-
guard intervals.
Support for STBC (space-time block coding) and LDPC (Low Density Parity Check) codes.
Improved 11n performance due to features such as 11n frame aggregation (A-MPDU and A-MSDU) and
low-overhead host-assisted buffering (RX A-MSDU and RX A-MPDU). These techniques can improve
performance and efficiency of applications involving large bulk data transfers such as file transfers or high-
resolution video streaming.

Feature
Description
System Clocking
(RTC Block)
An RTC block controls the clocks and power going to other internal modules. Its inputs
contain sleep requests from these modules and its outputs contain clock enable and
power signals which are used to gate the clocks going to these modules. The RTC block
also manages resets going to other modules with the device. The M2US50NBT/
M2SD50NBT’s clocking is grouped into two types: high-speed and low-speed.
High Speed Clocking
The reference 26 MHz clock source drives the PLL and RF synthesizer of Wi-Fi and
Bluetooth. To minimize power consumption, the reference clock source is powered off in
SLEEP, HOST_OFF, and OFF states.
Low Speed Clocking
These modules require an external sleep clock (32.768 KHz) source from host platform
through pin-50 on the NFGG golden finger. It is used to place BT into deep sleep mode. For
Wi-Fi only application, it is needed.
Interface Clock
The host interface clock represents another clock domain for the
M2US50NBT/M2SD50NBT. This clock comes from the SDIO and is independent from the
other internal clocks. It drives the host interface logic as well as certain registers which can
be accessed by the host in HOST_OFF and SLEEP states.
MAC/BB/RF Block
The M2US50NBT/M2SD50NBT Wireless MAC consists of five major blocks:
Host interface unit (HIU) for bridging to the AHB for bulk data accesses and APB for
register accesses
Ten queue control units (QCU) for transferring TX data
Ten DCF control units (DCU) for managing channel access
Protocol control unit (PCU) for interfacing to baseband
DMA receive unit (DRU) for transferring RX data
Baseband Block
The M2US50NBT/M2SD50NBT baseband block (BB) is the physical layer controller for the
802.11b/g/n air interface.
It modulates data packets in the transmit direction
Detects and demodulates data packets in the receive direction.
It has a direct control interface to the radio to enable hardware to adjust analog gains
and modes dynamically.
Clock Sharing
Clock sharing is implemented on the M2US50NBT/M2SD50NBT. The Bluetooth chip
(CSR8811) receives a reference clock from the Wi-Fi chip (QCA6004). When Wi-Fi is in
power off/reset state, Bluetooth is also off.
External 32.768 KHz signal present on pin 50 allows the BT chip to go into deep sleep
mode and consume lowest amount of power

BLUETOOTH FUNCTIONAL DESCRIPTION
The M2US50NBT/M2SD50NBT Bluetooth (BT) block is based on the CSR8811A08 and described in the Table 3.
Table 3: Bluetooth functions
Feature
Description
HCI-UART Interface
The UART Interface is a standard high-speed UART interface. It operates up to 4 Mbps,
supporting Bluetooth HCI UART interface.
PCM or I2S Interface
Continuous PCM encoded audio data transmission and reception over Bluetooth
Processor overhead reduction through hardware support for continual
transmission and reception of PCM data
A bi-directional digital audio interface that routes directly into the baseband layer
of the firmware. It does not pass through the HCI protocol layer
Hardware on CSR8811 for sending data to and from a SCO connection
Up to three SCO connections on the PCM interface at any one time
PCM interface master, generating PCM_SYNC and PCM_CLK
PCM interface slave, accepting externally generated PCM_SYNC and PCM_CLK.
Various clock formats including:
– *Long Frame Sync
– *Short Frame Sync
GCI timing environments
13-bit or 16-bit linear, 8-bit μ-law or A-law companded sample formats
Receives and transmits on any selection of three of the first four slots following
PCM_SYNC
The PCM configuration options are enabled by setting SKEY_PCM_CONFIG32
CPU and Memory
Uses a 16-bit RISC MCU for low power consumption and efficient use of memory.
The MCU, interrupt controller, and event timer run the Bluetooth software stack
and control the Bluetooth radio and host interfaces.
56 KB of on-chip RAM is provided to support the RISC MCU and is shared between
the ring buffers used to hold voice/data for each active connection and the
general-purpose memory required by the Bluetooth stack.
5 Mb of Internal ROM memory is available on the CSR8811. This memory is
provided for system firmware, storing CSR8811 settings and program code.
Build-in Standard
WLAN Coexistence
The M2US50NBT/M2SD50NBT internally supports the standard WLAN coexistence
interface through the WLAN_ACTIVE, BT_PRIORITY, and BT_ACTIVE pins.
Reference Clock
The BT block is configured for 26 MHz reference clock frequency. The clock source is
provided to BT internally from the WLAN block on demand from BT_CLK_REQ.
Note: The WLAN block must be initialized prior before BT clock sharing is enabled.
BT Low Energy
Supports Low Energy specification which allows for connections to devices with single
mode LE function (such as a watch, sensor, and HID). The implementation is optimized
for coexistence with WLAN.
BT_RFKILL
The NGFF pin-54 is connected to (BT_PWD_L) resets and powers down the BT block.
Holding the pin-54 at Low state turns off the entire BT block; all state information is
lost. To ensure a full reset, the reset signal should be asserted for a period greater
than five milliseconds.

Feature
Description
Radio
The BT radio shares the single antenna port with the WLAN through an internal three-
way RF switch. The M2US50NBT/M2SD50NBT implements WLAN/BT coexistence
internally.
VDDIO is to set the I/O voltage internally with either 1.8 V or 3.3 V to ensure same
voltage level for the internal Wi-Fi and BT coexistence signal. Refer to the reference
design specifications for details.
ELECTRICAL CHARACTERISTICS
Absolute Maximum Ratings
Table 4 summarizes the absolute maximum ratings and Table 5 lists the recommended operating conditions for
the M2US50NBT/M2SD50NBT. Absolute maximum ratings are those values beyond which damage to the device
can occur. Functional operation under these conditions, or at any other condition beyond those indicated in the
operational sections of this document, is not recommended.
Note: Maximum rating for signals follows the supply domain of the signals.

RF LAYOUT DESIGN GUIDELINES/PRECAUTIONS
The following is a list of RF layout design guidelines and recommendation when installing a Laird 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.
If there are other radios or transmitters located on the device (such as a Bluetooth radio), place the devices
as far apart from each other as possible. Also, make sure there are at least 25dB isolation between
Bluetooth antenna and Wi-Fi antenna.
Laird recommends the use of a double shielded cable for the connection between the radio and the
antenna elements.
Be sure to put the capacitor on the power pin as close as possible to reduce the radiation issue.
Use proper electro-static-discharge (ESD) procedures when installing the Laird radio module.
In order to get maximum throughput when operate at MIMO 2x2, two antennas with at least 25dB isolation
is recommended.
To avoid negatively impacting TX power and receiver sensitivity, do no cover the antennas with metallic
objects or components.
Opening/handing/removing must be done on an anti-ESD treated workbench.
All workers must also have undergone anti-ESD treatment.
The devices should be mounted within one year of the date of delivery.
