Operational Description of a wirelessdevice to connect to SMART TV

- Features

>IEEE 802.11ac Draft compliant.

>Dual-band 2.4GHz /5 GHz

>Dual-stream spatial multiplexing up to 600Mbps data rate

>Support 20,40,80MHz channel with optional SGI(256QAM modulation)

>On-chip power amplifiers and low noise amplifiers for both bands

>Complies with Bluetooth Core Specification Version 5.0

>Supports BT/Wi-Fi coexistence.

>Adaptive frequency hopping (AFH) for reducing radio frequency interference

- Time base of the RF frequency For IF and RF frequency, 40MHz crystal is a clock reference.

- Synthesizer Synthesizer inside Transceiver. Internal voltage controlled oscillator (VCO) provides the desired LO signal base on the phase-locked loop (PLL) with a relatively wide tuning range for this application. Internal fractional nPLL allows support for a wide range of reference clock frequencies

- Wi-Fi Transmission Baseband data is modulated and up converted to the 2.4GHz ISM and 5-GHz U-NII bands,respectively. Linear on chip power amplifier are included, which are capable of delivering high output powers while Meeting IEEE802.11ac and IEEE802.a/b/g/n specifications without the need for external PAs.When using the internal PAs, closed-loop output power control is completely integrated.Base-band Processing (BBP) IC has DSSS

(BPSK/QPSK/CCK) and OFDM(BPSK/QPSK/16QAM/64QAM/25QAM) modulation function, it provides transmission data rate are 1, 2, 5.5, 11Mbps on DSSS and 6, 12, 18, 24, 36, 48, 54 Mbps on OFDM. Digital data signal will be converted toanalog (TX IQ) signals through DAC in BBP IC, TX IQ pass through to low pass filter. TX I/Q signaluse direct conversion (zero-IF) architecture converter to generate carrier frequency signal. Transceiver IC and internal PA magnify output power.

- Wi-Fi Receiver The MT7668AUN has a wide dynamic range, direct conversion receiver that employs high-order on-chip channel filtering to ensure reliable operation in the noisy 2.4GHz ISM band or the entire 5GHz U-NII band

.Control signals are available that can support the use of optional LNAs for each band,which can increase the receive sensitivity by several decibels.Reverse direction isolation of LNA inside Transceiver IC suppresses unwanted radiation. Then RFsignal will be directly down to IF signal (RX IQ) and high frequency spurious emissions are suppressed by LPF. At last RX IQ signal will be demodulated digital data.

-Bluetooth Low Energy The WCT732M support the Bluetooth 4.2 LE and 5.0 BLE 2Mbps

- Link Control Layer The link control layer is part of the Bluetooth link control functions that are implemented in dedicated logic in the link control unit(LCU). Each task performs a different state in the Bluetooth Link Controller.

- Wideband speech The WCT732M provides supports for wideband speech(WBS) using on-chip Smart Audio technology. The WCT732M can perform modified Sub Band Codec(mSBC) encoding and decoding of linear 16bitsat 16kHz(256kbps rate) transferred over USB interface.

- Adaptive Frequency Hopping The WCT732M gathers link quality statistics on a channel by basis to facilitate channel assessment and Channel map selection. The link quality is determined using both RF and baseband signal processing to Provide a more accurate frequency-hop map.
