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
    • Supports Full-speed (12Mbps) and High-speed (480Mbps)
  • Embedded standard 8051 CPU with enhanced features:
    • Four cycles per instruction
    • Variable clock speed cuts power consumption
  • Supports 9 endpoints:
    • 64-Byte buffer for control endpoint
    • Two 512-Byte buffers for bulk IN endpoint
    • Seven 512-Byte buffers for bulk OUT endpoint
  • 3.3V and 1.5V power supplies required
  • 5V tolerant I/Os
  • 0.15μm CMOS process
