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.

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

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.

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.

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.

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 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.
