rtl8188re datasheet single-chip ieee 802.11b/g/n 1t1r wlan controller with pci express interface 1 track id: jatr-2265-11 rev. 1.0 1. general description the realtek RTL8188RE-GR is a highly integrated single-chip wireless lan (wlan) pci express network interface controller compatible with th e 802.11n specification. it combines a mac, a 1t1r capable baseband, and rf in a single chip. the rtl8188re provides a complete solution for a high throughput performance wireless client. the rtl8188re baseband implements orthogonal fr equency division multiplexing (ofdm) with 1 transmit and 1 receive path and is compatible with the ieee 802.11n specification 2.0. 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 convolutiona l 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 rtl8188re builds in an enhanced signal detect or, an adaptive frequency domain equalizer, and a soft-decision viterbi decoder to alleviate severe multi-pa th effects and mutual interference in the reception of multiple streams. robust interference detecti on and suppression are provided to protect against bluetooth, cordless phone, and microwave oven interference. efficient iq-imbalance, dc offset, phase noise, fre quency 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 rtl8188re 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 rtl8188re mac supports 802.11e for multimedia applications, 802.11i for security, and 802.11n for enhanced mac protocol efficienc y. using packet aggregation techniques such as a-mpdu with ba and a-msdu, protocol efficien cy is significantly improved. power savi ng mechanisms such as legacy power save, and u-apsd, and apsd, reduce the power wasted during idle time, and compensates for the extra power required to transmit ofdm. the rtl8188r e provides simple legacy and 20mhz/40mhz co-existence mechanisms to ensure backward and network compatibility. www.datasheet.co.kr datasheet pdf - http://www..net/
