SX-SDMAC

802.11ac Plus Bluetooth SDIO Module

The Silex SX-SDMAC is a dual-band IEEE802.11a/b/g/n/ac WLAN

plus Bluetooth 5.0 BR/EDR/BLE “Smart Ready” SDIO module based

on the latest Qualcomm Atheros Technology. It integrates a

QCA9377 SoC with MAC, Baseband, RF, RF front end, and peripheral

circuitry. SX-SDMAC operates on a +3.3V main power supply and

selectable +1.8V/+3.3V IO power supply.

The SX-SDMAC comes in surface mount (SMT) and board to board

connector (B2B) form factors. The SX-SDMAC has a 50 ohm U.FL

connector as a connection interface for an external antenna. There

is also an option to use an onboard chip antenna for the surface

mount (SMT) version.

SX-SDMAC supports 802.11ac Wave 2 multi-user MIMO (MU-MIMO)

client which can increase the overall WLAN system performance.

SX-SDMAC provides an SDIO 3.0 interface for WLAN and a hi-speed

UART interface for BT.

The SX-SDMAC is a FCC/IC/CE/MIC certied module. In order to

expedite your product development process, Silex can provide

both hardware and software engineering services including

custom driver development, as well as turnkey product design and

manufacturing.
