Product Description
Realtek Mini Pci-e WLAN Card RTL8187B
128-Pin LQFP with ‘Green?package
State machine implementation without external memory (RAM, flash) requirement
Complies with IEEE 802.11 b/g standards
Supports descriptor-based buffer management
Integrated Wireless LAN MAC and Direct Sequence Spread Spectrum/OFDM Baseband Processor in one chip
Enhanced signal detector, adaptive frequency domain equalizer, and soft-decision Viterbi decoder to alleviate severe multipath effects
Processing Gain compliant with FCC
On-Chip A/D and D/A converters for I/Q Data, AGC, and Adaptive Power Control
Supports both transmit and receive Antenna Diversity
Data rates of 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54Mbps
Supports 40MHz OSC as the internal clock source. The frequency deviation of the OSC must be within 25 PPM on IEEE 802.11g
IEEE 802.11g protection mechanisms for both RTS/CTS and CTS-to-self
Burst-mode support for dramatically enhanced throughput
DSSS with DBPSK and DQPSK, CCK modulations and demodulations supported with long and short preamble
OFDM with BPSK, QPSK, 16QAM and 64QAM modulations and demodulations supported with rate compatible punctured convolutional coding with coding rate of 1/2, 2/3, and 3/4
Efficient IQ-imbalance calibration, DC offset, phase noise, frequency offset and timing offset compensation reduce analog front-end impairments
Selectable digital transmit and receiver FIR filters provided to meet transmit spectrum mask requirements and to reject adjacent channel interference
Programmable scaling both in transmitter and receiver to trade quantization noise against the increased probability of clipping
Fast receiver Automatic Gain Control (AGC) & antenna diversity functions
Complies with WMM, 802.11e, and CCX specifications
Complies with 802.11h, 802.11i, 802.11j specifications
Hardware-based IEEE 802.11i encryption/decryption engine, including 64-bit/128-bit WEP, TKIP, and AES
Supports Wi-Fi alliance WPA and WPA2 security
Contains two large independent transmit and receive FIFO buffers
Advanced power saving mode when the LAN and wakeup function are not used
Uses 93C46 (64*16-bit EEPROM) or 93C56 (128*16-bit EEPROM) to store resource configuration and ID parameter data
LED pins for various network activity indications
Six GPIO pins supported
Supports digital loopback capability on both ports
Scatter and gather operation
Complies with USB Specification 2.0
