Chip Block Diagram
The BCM21551 is an advanced, single-chip, 65-nm HSUPA/WCDMA/
EDGE SoC with fully integrated 2G and 3G RF transceivers, Bluetooth,
FM and mixed-signal analog. Based on 65-nm technology, the
BCM21551 offers the highest integration, lowest power consumption,
and lowest cost HSUPA solution.
The modem supports 5.8 Mbps HSUPA, 7.2 Mbps HSDPA, WCDMA
384K with Class 33 EDGE modem and integrates all analog and digital
functions on a single, monolithic silicon.
The integrated BCM21551 RF transceiver design delivers high RF
performance while achieving low power consumption through innovative
architecture and circuit design. The RF transceiver draws on Broadcom's
extensive experience in bulk CMOS radio design and directly leverages
Broadcom's BCM2085 and BCM21331 CMOS cellular radio products.
Critical radio performance, while using digital CMOS for radios, is assured
through the use of proprietary, autonomous, real-time calibrations within
the radio.
The BCM21551 integrates Bluetooth 2.1 (Lisbon) + EDR-compliant and
FM/ RDS/RBDS transceivers. The Bluetooth and FM core feature a high
level of integration and eliminates all critical external components, thereby,
minimizing the system’s footprint, power consumption, and cost.
Robust multimedia capabilities are also provided, including 30 fps HVGA
video for H.264 and WMV9, a 5-Mpixel camera with ISP, extensive audio
codec support for music playback, and 2D graphics/blending for the LCD.
The BCM21551 cellular processor has fully integrated audio support for
driving the ear piece, ringer and stereo headsets. It also has stereo line
drivers to support the external Class D amplifiers for driving loudspeakers.
External audio/video coprocessors are not required for the handset design.
Broadcom's proprietary M-Stream high-performance modem and SAIC
advanced signal processing technologies improve cellular handset
reception and voice quality while increasing network capacity and without
sacrificing call quality. The BCM21551 utilizes an advanced release 6-
compliant direct Matrix Inversion (DMI) equalizer for high HSDPA data
throughput in the most challenging radio conditions, thereby offering high
performance without costly receiver diversity.
S
ECURITY
Enhanced security is provided through One-Time Programmable (OTP)
bits and dedicated hardware blocks for secure Boot, memory and DRM
functions. The embedded OTP bits allow the software to boot securely and
verify IMEI security prior to network activation. The OTP bits can also be
used by high-level applications to verify the integrity of Digital Rights
Management (DRM) functions.
