1. General Description

The Realtek RTL8723DU is a highly integrated single-chip 802.11b/g/n 1T1R WLAN, and an

integrated Bluetooth 2.1/4.2 single chip with USB 2.0 multi-function. It combines a WLAN MAC, a

1T1R capable WLAN baseband, BT Protocol Stack (LM, LL, and LE), BT Baseband, modem, and

WLAN/BT RF in a single chip. The RTL8723DU provides a complete solution for a high-performance

integrated wireless LAN and Bluetooth controller. The RTL8723DU WLAN baseband implements

Orthogonal Frequency Division Multiplexing (OFDM) with 1 transmit and 1 receive path and is

compatible with the 802.11n specification. Features include one spatial stream transmission, short

guard interval (GI) of 400ns, spatial spreading, and transmission over 20MHz and 40MHz bandwidth.

For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying

(CCK) and OFDM baseband processing are included to support all 802.11b and 802.11g data rates.

Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling

capability, are available, and CCK provides support for legacy data rates, with long or short preamble.

The high-speed FFT/IFFT paths, combined with BPSK, QPSK, 16QAM, and 64QAM modulation of

the individual subcarriers and rate compatible punctured convolutional coding with coding rate of 1/2,

2/3, 3/4, and 5/6, provide higher data rates of 54Mbps and 150Mbps for 802.11g and 802.11n OFDM

respectively.

A built-in enhanced signal detector, adaptive frequency domain equalizer, and a soft-decision Viterbi

decoder help to alleviate multi-path effects and mutual interference in the reception of multiple streams.

Robust interference detection and suppression are provided to protect against Bluetooth, cordless phone,

and microwave oven interference.

Efficient IQ-imbalance, DC offset, phase noise, frequency offset, and timing offset compensations are

provided for the radio frequency front-end. Selectable digital transmit and receive FIR filters are

provided to meet transmit spectrum mask requirements and to reject adjacent channel interference,

respectively.

The RTL8723DU WLAN Controller supports fast receiver Automatic Gain Control (AGC) with

synchronous and asynchronous control loops among antennas, antenna diversity functions, and

adaptive transmit power control function to obtain better performance in the analog portions of the

transceiver.

The RTL8723DU WLAN MAC supports 802.11e for multimedia applications, 802.11i for security,

and 802.11n for enhanced MAC protocol efficiency. Using packet aggregation techniques such as

A-MPDU with BA and A-MSDU, protocol efficiency is significantly improved. Power saving

mechanisms such as Legacy Power Save, and U-APSD, reduce the power wasted during idle time, and

compensate for the extra power required to transmit OFDM. The RTL8723DS-VC provides simple

legacy and 20MHz/40MHz co-existence mechanisms to ensure backward and network compatibility.

The RTL8723DU Bluetooth controller complies with Bluetooth core specification v4.2, and supports

dual mode (BR/EDR + Low Energy Controllers). It is backward compatible with previous versions
