BCM4329
Preliminary Data Sheet
BCM4329
Single Chip IEEE 802.11™ a/b/g/n MAC/Baseband/Radio
with Integrated Bluetooth 2.1 + EDR and FM Transceiver
GENERAL DESCRIPTION
The Broadcom® BCM4329 family of single chip
devices provides for the highest level of integration
for a mobile or handheld wireless system, with
integrated IEEE 802.11™ a/b/g and handheld device
class 802.11n (MAC/baseband/radio), Bluetooth® 2.1
+ EDR (Enhanced Data Rate), and FM radio receiver
and transmitter. It also integrates 2.4 GHz and 5 GHz
WLAN CMOS power amplifiers to meet the
requirements of most handheld systems while
permitting an external power amplifier for even high
power applications. The BCM4329 is designed to
address the needs of highly mobile devices that
require minimal power consumption and compact
size.
Utilizing advanced design techniques and process
technology to reduce active and idle power, the
BCM4329 extends the system battery life while
maintaining robust connectivity and still provides a
rich set of features.
The BCM4329 implements the highly sophisticated
Enhanced Collaborative Coexistence radio
coexistence algorithms and hardware mechanisms,
allowing for an extremely collaborative Bluetooth
coexistence scheme along with coexistence support
for external radios (such as GPS, WiMax, or Ultra
Wide-Band radio technologies, as well as cellular
radios) and a single shared antenna (2.4-GHz antenna
for Bluetooth and WLAN). As a result, enhanced
overall quality for simultaneous voice, video, and
data transmission on a handheld system is achieved.
In addition, the BCM4329 integrates a power
management unit, simplifying the power topology on
a system, and allowing for operation directly from
the mobile platform battery.
Along with integrated power amplifiers, the
BCM4329 also includes integrated transmit and
receive baluns, further reducing the overall solution
cost.
