1Theory of Operation
The Marvell® SP88W8782-MA0 2.4 GHz v2.0 (HP SDGOB-1292, 1150-7962) IEEE 802.11n/g/b
WLAN client module is a low cost, low part count, complete, and ready-to-manufacture solution
using a standard SDIO interface. The design architecture includes the Marvell® 88W8782, a highly
integrated WLAN System-on-Chip (SoC), specifically designed to support high throughput data rates
for next generation WLAN products. The device is designed to support IEEE 802.11n/g/b payload
data rates.
The module provides the combined functions of the IEEE Standard 802.11/802.11b Direct Sequence
Spread Spectrum (DSSS), 802.11g and 802.11n Orthogonal Frequency Division Multiplexing
(OFDM), baseband modulation, Medium Access Controller (MAC) with support for multiple BSS and
multiple station modes, CPU, memory, host interface, direct-conversion WLAN RF radio, and
Bluetooth coexistence on a single integrated chip. Also included are an integrated 2.4 GHz power
amplifier and an integrated 2.4 GHz transmit/receive switch.
The transceiver architecture design is equipped with a fully integrated RF-to-baseband radio that
operates in the 2.4 GHz ISM radio band for 802.11 applications. For optimum performance, the gain
adjustments of the integrated LNAs and AGCs on the receive paths are seamlessly controlled by
baseband functions. The transmitters up-convert their quadrature baseband signals and deliver the
signals to a fully integrated internal power amplifier for radio band transmission. One external Single
Pole Double Throw (SPDT) switch provides antenna diversity. 2.4 GHz T/R switching is provided by
an integrated T/R switch.
The 40 MHz crystal provides the SoC with the reference frequency. Local oscillator frequencies are
generated by a fully integrated programmable frequency synthesizer with no external components.
The loop bandwidth is optimized for phase noise and dynamic performance and quadrature signals
are generated on-chip.
The chip architecture also includes integrated One-Time Programmable (OTP) memory for storing
calibration and wireless module configuration parameters such as the MAC address. An optional
external serial memory chip may also be used to store firmware, calibration data, and wireless
module configuration parameters.
For security, the 88W8782 supports IEEE 802.11i security standards through the implementation of
the Advanced Encryption Standard (AES)/Counter Mode CBC-MAC Protocol (CCMP) and Wired
Equivalent Privacy (WEP) with Temporal Key Integrity Protocol (TKIP) security mechanisms.
For video, voice, and multimedia applications, 802.11e Quality of Service (QoS) is supported.
