1. General Description
The Realtek RTL8188ETV is a highly integrated single-chip 802.11n Wireless LAN (WLAN) network USB
interface (USB 1.0/1.1/2.0 compliant) controller. It combines a WLAN MAC, a 1T1R capable WLAN
baseband, and WLAN RF in a single chip. The RTL8188ETV provides a complete solution for a high
throughput performance integrated wireless LAN device.
The RTL8188ETV WLAN baseband implements Orthogonal Frequency Division Multiplexing (OFDM)
with 1 transmit and 1 receive path and is compatible with the IEEE 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 IEEE 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 IEEE 802.11g and 802.11n OFDM respectively.
The RTL8188ETV WLAN Controller 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.
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 RTL8188ETV 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 the better performance in the analog portions of the transceiver.
The RTL8188ETV 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
