BCM4354
Single-Chip 5G Wi-Fi IEEE 802.11ac 2×2 MAC/
Baseband/Radio with Integrated Bluetooth 4.1
and FM Receiver
GENERAL DESCRIPTION
The Broadcom^® BCM4354 is a complete dual–band
(2.4 GHz and 5 GHz) 5G Wi–Fi 2 × 2 MIMO^® MAC/
PHY/Radio System–on–a–Chip. This Wi–Fi single–
chip device provides a high level of integration with
dual–stream IEEE 802.11ac MAC/baseband/radio,
Bluetooth 4.1, and FM radio receiver. In IEEE
802.11ac mode, the WLAN operation supports rates
of MCS0–MCS9 (up to 256 QAM) in 20 MHz, 40 MHz,
and 80 MHz channels for data rates up to 867 Mbps.
In addition, all the rates specified in IEEE 802.11a/b/
g/n are supported. Included on–chip are 2.4 GHz and
5 GHz transmit power amplifiers and receive low
noise amplifiers.
For the WLAN section, several alternative host
interface options are included: an SDIO v3.0 interface
that can operate in 4b or 1b modes, a high-speed
inter-chip (HSIC) interface, and a PCIe v3.0 compliant
interface running at Gen1 speeds. For the Bluetooth
section, host interface options of a high-speed 4-wire
UART and USB 2.0 full-speed (12 Mbps) are
provided.
The BCM4354 uses advanced design techniques and
process technology to reduce active and idle power,
and includes an embedded power management unit
that simplifies the system power topology.
In addition, the BCM4354 implements highly
sophisticated enhanced collaborative coexistence
hardware mechanisms and algorithms that ensure
that WLAN and Bluetooth collaboration is optimized
for maximum performance. Coexistence support for
external radios (such as LTE cellular and GPS) is
provided via an external interface. As a result,
enhanced overall quality for simultaneous voice,
video, and data transmission on a handheld system is
achieved.
