RTL8192SE

Datasheet

1. General Description

The Realtek RTL8192SE is a highly integrated single-chip MIMO (Multiple In, Multiple Out) Wireless

LAN (WLAN) solution for the wireless high throughput 802.11n draft specification. It combines a MAC, a

2T2R capable baseband, and RF in a single chip. The RTL8192SE provides a complete solution for a high

throughput performance wireless client.

The RTL8192SE baseband implements Multiple Input, Multiple Output (MIMO) Orthogonal Frequency

Division Multiplexing (OFDM) with 2 transmit and 2 receive paths (2T2R) and is compatible with the

IEEE 802.11n Draft specification 2.0. Features include two spatial streams transmission, short guard

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

RTL8192SE also supports explicit sounding packet feedback that helps senders with beamforming

capability. With 2 independent RF blocks, the RTL8192SE 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 and 802.11g data rates.

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

are available along with complementary code keying to provide the data rates of 1, 2, 5.5 and 11Mbps 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, provides the maximum data rate of 54Mbps and 300Mbps for IEEE

802.11g and 802.11n MIMO OFDM respectively.

The RTL8192SE builds in an enhanced signal detector, an adaptive frequency domain equalizer, and a

soft-decision Viterbi decoder to alleviate the 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 2 receive paths are implemented. Robust interference detection and suppression are

provided to protect against bluetooth, cordless phone, and microwave oven. Receive vector diversity for

multi-stream application is implemented for efficient utilization of MIMO channel. Efficient IQ-imbalance,

DC offset, phase noise, frequency offset and timing offset compensations are provided for the radio

frequency front-end impairments. Selectable digital transmit and receiver FIR filters are provided to meet

transmit spectrum mask requirements and to reject adjacent channel interference, respectively.
