SG901-1071
SG901-1071 Miniature Wi-Fi Radio
Overview
The SG901-1071 WiFi module is optimized to
simplify successful integration into systems
requiring the latest performance with small size.
This module is a highly integrated single chip
based 802.11b/g/n WLAN radio for embedded,
low-power and extremely small form factor mobile
applications. The product conforms to the IEEE
802.11B, G, and N protocols operating in the
2.45GHz ISM frequency band supporting 802.11n
modulations up to 72.2Mbps, all 802.11g OFDM
modulations, and all mandatory 802.11b
modulations.
The SG901-1071 is a fully integrated wireless
radio including RF Synthesizer/VCO, high-speed
data converters, digital baseband processor,
onboard MAC and PHY processors, Power
Management, Power Amplifier, and LNA.
An on-board EEPROM stores calibration data for
alignment-free
integration.
No
customer
calibration required.
Bluetooth integration features of the radio are
made available.
An on-board crystal and filter simplify system
integration. The addition of 1.8V, 3.3V, and VIHO
supplies, Antenna, and host communication,
provides a complete WiFi solution. For maximum
flexibility, the SG901-1071 can be optionally
supplied without internal oscillator and accept a
wide range of external reference clock
frequencies.
Host control is provided by either an SDIO or SPI
interface.
