1. General Description
The Realtek RTL8192DE is a highly integrated single-chip MIMO (Multiple In, Multiple Out) Wireless
LAN (WLAN) PCI Express network interface controller complying with the wireless high throughput
IEEE 802.11n specification. It combines a configurable dual MAC, 2T2R capable baseband and
2.4GHz/5GHz band RF in a single chip. The RTL8192DE provides a complete solution for a
high-performance wireless client.
The RTL8192DE implements dual MAC by PCI Express multi-function capability. The dual MAC feature
enables RTL8192DE to access two different wireless networks and to act as an WiFi station and an AP
concurrently. The RTL8192DE also supports WiFi Direct feature that can easily build a WiFi P2P PAN
network.
The RTL8192DE baseband implements Multiple Input, Multiple Output (MIMO) Orthogonal Frequency
Division Multiplexing (OFDM) with two transmit and two receive paths (2T2R). Features include two
spatial stream transmissions, short Guard Interval (GI) of 400ns, spatial spreading, and support for both
20MHz and 40MHz channel bandwidth. Moreover, RTL8192DE provides one spatial stream space-time
block code (STBC) to extend the range of transmission. At the receiver, extended range and good minimum
sensitivity is achieved by having receiver diversity up to 2 antennas. As the recipient, the RTL8192DE also
supports explicit sounding packet feedback that helps senders with beamforming capability. With 2
independent RF blocks, the RTL8192DE can perform fast roaming without link interruption.
For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying (CCK)
and OFDM baseband processing are included to support all IEEE 802.11b, 802.11g and 802.11a 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 the higher data rates than 54Mbps upto 300Mbps for IEEE 802.11n MIMO OFDM respectively.
The RTL8192DE builds in an enhanced signal detector, an adaptive frequency domain equalizer, and a
soft-decision Viterbi decoder to alleviate severe multi-path effects and mutual interference in the reception
of multiple streams. For better detection quality, receive diversity with Maximal-Ratio-Combine (MRC)
applying up to two receive paths is implemented. Robust interference detection and suppression are
provided to protect against Bluetooth, cordless phone, and microwave oven interference.
Receive vector diversity for multi-stream application is implemented for efficient utilization of the MIMO
channel. 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 RTL8192DE supports fast receiver Automatic Gain Control (AGC) with synchronous and
asynchronous control loops among antennas, antenna diversity functions, and adaptive transmit power
control functions to obtain better performance in the analog portions of the transceiver.
The RTL8192DE MAC supports 802.11e for multimedia applications, 802.11i and WAPI (Wireless
Authentication Privacy Infrastructure) 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, U-APSD, and MIMO
power saving reduce the power wasted during idle time, and compensate for the extra power required to
transmit MIMO OFDM. The RTL8192DE provides simple legacy and 20MHz/40MHz co-existence
mechanisms to ensure backward and network compatibility.
