1. Product Description
The Qualcomm Atheros QCA9880 is a highly integrate wireless local area network(WLAN)system-on-chip(SoC)for 5 GHz 802.1ac or 2.4/5GHZ 802.11n WLAN applictions. The QCA9880 integrates an on-board CPU for low-level setup of WLAN physical layer (PHY) and RF spatial streams for wireless applictions demanding the highest robust link quality and maximum throughput and range. The QCA9880 integrates a multi-protocol MAC, PHY, analog-to-digital/digtial-to-analog converters(ADC/DAC),3x3 MIMO radio transvceivers, and PCI Express interface in an all-CMOS device for low power consumption and small form-factor applictions.
The QCA9880 implemets half-duplex OFDM,CCK, and DSSS PHY, supporting 1.3 GBps for 802.11ac 80 MHz channel operation. It supports 802.11n up to 216.7 Mbps for 20 MHz and 450 Mbps for 40 MHz channel opeartions, and IEEE 802.11a/b/g data rates. Additonal features include Maxmal Likelihood(ML)decoding, Low-Density Partity Check (LDPC), Maximal Ratio Combining (MRC), Spac Time Block Code (STBC), and On-Chip One-Time Programmadble (OTP) memory to eliminate the need for an external flash and to further reduce the external component count and BOM cost. The QCA9880 supports 802.11i security, Rx/Tx filtering, error recovery, and 802.lle quality of service (QoS).
The QCA9880 supports up to three simultaneous traffic streams integrating three Tx amd three 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 to multiple antennas. Rx chains use an integrated architecture. The frequency synthesizer supports 1-MHz steps to match frequencies defined by IEEE 802.11a/b/g/n specification. The QCA9880 supports frame data transfer to and from the host using a PCIE interface providing interrupt generation and reporting, power save, and status reporting. Other external interfaces include EEPROM and GPIOs.
