Product brief

1 Product overview
The IW611 is a highly integrated 2.4/5GHz dual-band 1x1 Wi-Fi 6 and Bluetooth/Bluetooth Low Energy 5.2 single-chip solution optimized for a broad array of IoT and Industrial applications in smart home, smart devices and accessories, smart appliances, smart energy, industrial automation, gateways and many more. This high degree of integration contributes to very low system costs and a minimum external BOM while achieving efficient co-existence between all internal radios as well as external radios.
IW611 includes a full-feature Wi-Fi subsystem powered by NXP's 802.11ax (Wi-Fi 6) technology bringing higher throughput, better network efficiency, lower latency and improved range over previous generation Wi-Fi standards. The Wi-Fi subsystem integrates a Wi-Fi MAC, baseband, and direct-conversion radio with integrated PA, LNA, and transmit/receive switch removing the need for an RF front end module (FEMs), saving cost ,and reducing system complexity.
In addition to a Wi-Fi 6 radio, the IW611 integrates an independent Bluetooth 5.2 subsystem that supports Bluetooth and Bluetooth Low Energy (LE). The device features Bluetooth Profiles such as hands free (HFP), advanced audio distribution profile (A2DP) for audio streaming as well as additional profiles like dual wide band speech (WBS). For Bluetooth Low Energy, the IW611 enables 2Mbit/s high speed data rate, long range, and extended advertising. Finally, LE Audio is supported utilizing Isochronous channels for a better overall audio experience.
The IW611 supports two front-end antenna configurations: single-antenna (Figure 1) and dual antenna (Figure 2).
The IW611 integrates dedicated CPUs and memories for both the Wi-Fi and Bluetooth subsystems which enable real time, independent protocol processing. Interfaces for connecting the IW611 to external host processors include SDIO 3.0 for Wi-Fi and UART for Bluetooth.

3.4.1.2 Clock frequency and audio data resolutions
Audio data may arrive with different input data formats with different sampling rates.
In central5 mode, the I2S interface uses an audio input clock of 4.096 MHz or 2.048 MHz to provide the appropriate M clock (MCLK) and bit clock (I2S_BCLK) frequency to match the sampling rates of each audio data format. The sampling rates can be 8 kHz to 16 kHz.
In peripheral5 mode, the I2S interface does not provide the bit clock (I2S_BCLK) but it can provide the M clock (MCLK).

3.4.2.2 PCM modes of operation
The PCM interface supports two modes of operation: · PCM central8 · PCM peripheral8
When in PCM central8 mode, the interface generates a 2 MHz or a 2.048 MHz PCM_CLK and 8 kHz PCM_SYNC signal. An alternative PCM central8 mode is available that uses an externally generated PCM_CLK, but still generates the 8 kHz PCM_SYNC. The external PCM_CLK must have a frequency that is an integer multiple of 8 kHz. Supported frequencies are in the 512 kHz to 4 MHz range.
When in PCM peripheral8 mode, the interface has both PCM_CLK and PCM_SYNC as inputs, thereby letting another unit on the PCM bus generate the signals.
The PCM interface consists of up to four PCM slots (time divided) preceded by a PCM sync signal. Each PCM slot can be either 8 or 16 bits wide. The slots can be separated in time, but are not required to follow immediately after one other. The timing is relative to PCM_CLK. Figure 12 shows an example of a PCM burst with two slots.
The burst starts with a PCM_SYNC and then follows the PCM burst. In this example, the PCM burst consists of two PCM slots (the first slot is 8 bits wide, the second slot is 16 bits wide) separated with two PCM_CLK clock cycles. The PCM slots can be configured to start at an arbitrary point in time, and the start value is given relative to the start of the PCM_SYNC. The timing of the four PCM slots must be such that slot 0 is always located before slot 1, slot 1 before slot 2, etc. It is possible to only use for example slot 1 and not slot 0.
