RTL8192 Datasheet PDF – WLAN Controller – Realtek

Part Number : RTL8192, RTL8192CE, RTL8192SE

Function : Single-Chip IEEE 802.11b/g/n 2T2R WLAN Controller

Package : QFN-64 Pin

Manufacturers : Realtek Semiconductor

RTL8192 datasheet

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 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 specification. 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.
