QCA9994 Dual-Band 4x4 with 4 SS MIMO802.11 b/g/n/ac WLAN SoCDevice Specification
1Introduction1.1 General descriptionThe QCA9994 with Qualcomm® VIVETM 802.11ac technology is a highly integrated wireless local areanetwork (WLAN) system-on-chip (SoC) for 2.4 802.11n WLAN applications. The QCA9994 is a syn-thesizer WLAN radio. It includes aCPU and memory for WLAN media access layer (MAC) and physical layer (PHY) management andprovides host offload of other high-level networking tasks. It enables high-performance 4x4 MIMO with 4spatial streams for wireless applications demanding the highest robust link quality and maximumthroughput and range, plus 4 spatial stream MU-MIMO. The QCA9994 integrates a multi-protocol MAC,PHY, analog-to-digital/digital-to-analog converters (ADC/DAC), 4x4 MIMO radio transceivers, and PCIEinterface in an all-CMOS device for low power consumption and small form-factor applications.The QCA9994 implements half-duplex OFDM, CCK, and DSSS PHY. In 2 GHz mode it supports up to346.7 Mbps for 20 MHz and 800 Mbps for 40 MHz channel operations, and IEEE 802.11b/g/n data rates. , Maximal Likelihood (ML) decoding, Low-Density Parity Check (LDPC), Maximal Ratio Combining (MRC), Space Time Block Code (STBC), and On-Chip OneTime Programmable (OTP) memory to elimi-nate the need for an external flash and to further reduce the external component count and BOM cost. The QCA9994 supports 802.11 wireless MAC protocol, 802.11i security, Wi-Fi offload, error recovery, and 802.11e quality of service (QoS).The QCA9994 supports up to four simultaneous spatial streams integrating four Tx and four Rx chains forhigh 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). Rxchains receive from antennas through external LNAs. The frequency synthesizer supports 1-MHz steps tomatch frequencies defined by IEEE 802.11b/g/n specifications. The QCA9994 supports frame datatransfer to and from the host using a PCIE interface that supports interrupt generation and reporting andstatus reporting. Other external interfaces include EEPROM and GPIOs.
