1.1 General description
The
4X4-5GH
with Qualcomm
®
VIVE
TM
802.11ac technology is a highly integrated wireless local area
network (WLAN) system-on-chip (SoC) for 5 GHz 802.11ac. The
4X4-5GH
is a synthesizer WLAN ra-
dio with 160 MHz and 80+80 MHz support. It includes a CPU and memory for WLAN media access
layer (MAC) and physical layer (PHY) management and provides host offload of other highlevel net-
working tasks. It enables high-performance 4x4 MIMO with 4 spatial streams for wireless applications
demanding the highest robust link quality and maximum throughput and range, plus 4 spatial stream
MU-MIMO. The
4X4-5GH
integrates a multi-protocol MAC, PHY, analog-to-digital/ digital-to-analog
converters (ADC/DAC), 4x4 MIMO radio transceivers, and PCIE interface in an allCMOS device for
low power consumption and small form-factor applications.
The
4X4-5GH
implements half-duplex OFDM, supporting 1.733 Gbps for 802.11ac 160/80+80/80 MHz
channel operation in 5 GHz mode, and IEEE 802.11a/n/ac data rates. Additional features include 802.11ac
explicit transmit beamforming (TxBF), 802.11 compatible implicit TxBF, multi-user MIMO (MU-
MIMO), Dynamic Bandwidth Switching, Per Packet Switching between 4SS/80 MHz and 2SS/160/80+80
MHz, Maximal Likelihood (ML) decoding, Low-Density Parity Check (LDPC), Maximal Ratio Combin-
ing (MRC), Space Time Block Code (STBC), and On-Chip OneTime Programmable (OTP) memory to
eliminate the need for an external flash and to further reduce the external component count and BOM cost.
The
4X4-5GH
supports 802.11 wireless MAC protocol, 802.11i security, Wi-Fi offload, error recovery,
and 802.11e quality of service (QoS).
The
4X4-5GH
supports up to four simultaneous spatial streams integrating four Tx and four Rx chains for
high throughput and extended coverage. Tx chains combine PHY in-phase (I) and quadrature (Q) signals,
convert them to the desired frequency, and drive the RF signal through external power amplifiers (PAs). Rx
chains receive from antennas through external LNAs. The frequency synthesizer supports 1-MHz steps to
match frequencies defined by IEEE 802.11a/b/g/n/ac specifications. The
4X4-5GH
supports frame data
transfer to and from the host using a PCIE interface that supports interrupt generation and reporting and
status reporting. Other external interfaces include EEPROM and GPIOs.
