Part Number: RTL8192CE-GR, RTL8192CE


Package: 64-pin QFN

Manufacturer: Realtek Semiconductor


RTL8192CE-GR datasheet controller


The Realtek RTL8192CE-GR 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 RTL8192CE provides a complete solution for a high throughput performance wireless client.

The RTL8192CE 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. Moreover, RTL8192CE 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 RTL8192CE also supports explicit sounding packet feedback that helps senders with beamforming capability. With 2 independent RF blocks, the RTL8192CE can perform fast roaming without link interruption. […]

The ALC887 is a 7.1 Channel High Definition Audio Codec with two independent SPDIF outputs.
Featuring eight channels of DAC support 7.1 sound playback, and integrates two stereo ADC that can
support a stereo microphone, and feature Acoustic Echo Cancellation (AEC), Beam Forming (BF), and
Noise Suppression (NS) for voice applications.

ALC887 is designed not only to meet the premium audio performance requirements in current WLP3.10
(Windows Logo Program), but provides better characteristics for future WLP. That brings user real high
fidelity of sound quality. […]



1. Meets premium audio requirements for Microsoft WLP 3.10
2. Meets stricter performance requirements for future WLP
3. High-performance DACs with 97dB Signal-to-Noise Ratio (SNR), ADCs with 90dB SNR
4. Four stereo DACs (8 channels) support 16/20/24-bit PCM format for 7.1 sound playback.
5. Two stereo ADCs (4 channels) support 16/20/24-bit PCM format recording simultaneously
6. All DACs supports 16/20/24-bit, 44.1k/48k/96k/192kHz sample rate
7. All ADCs supports 16/20/24-btt, 44.1k/48k/96k/192kHz sample rate
8. Two independent SPDIF-OUT converters support 16/20/24-bit, 44.1k/48k/88.2k/96k/192kHz sample
rate. One converter for normal SPDIF output, the other outputs an independent digital stream to the
HDMI transmitter
