• Manufacturer Part Number: bcm2070
• Description: Bcm2070 - Single-chip Bluetooth 2.1 Edr Hci Solution
• Manufacturer: Broadcom Corp.

The Broadcom BCM2070 is a monolithic, single-chip, stand-alone
baseband processor with a high performance integrated 2.4-GHz
transceiver for Bluetooth + EDR applications. It is fully compliant with
Bluetooth 2.1 and all prior standard features. Processed using advanced
65-nm LP CMOS technology, the BCM2070 offers unmatched
integrated solution with the smallest footprint and lowest cost of
implementing a Bluetooth system.
The use of the advanced 65-nm process enables the BCM2070 to achieve
the lowest possible current consumption in all modes of operation.
The BCM2070 has an architecture that has been designed to take
advantage of the EDR standard. Its superior integrated RF design enables
much higher output power and lower input sensitivity, which makes the
BCM2070 the ideal solution to support Bluetooth EDR. The built-in
Class 1 PA, which is capable of transmitting 10 dBm output power, can
be enabled with 1.8V power supply. Together with Broadcom’s leading
Packet Loss Concealment (PLC) technology, which effectively reduces
packet loss and bit error rates, the BCM2070 can effectively combat
interference and reduce dropped connections that result from distance

and physical obstructions. These translate directly into higher and more
reliable throughput and greater link-range performance. The BCM2070
also includes industry collaborative coexistence solutions with WLAN
and WiMAX systems. By using Broadcom’s proprietary packet
redistribution scheme, the BCM2070 is the industry's first Bluetooth
product that is capable of supporting up to five simultaneous A2DP
applications.
Ultra low-cost solutions can be achieved with the BCM2070 by using
standard chip-on-board assembly techniques using the WLBGA
package. Low-risk applications are enabled through the extensive
integration of external passive and active components. All sensitive RF
and analog portions of the Bluetooth radio and baseband have been
integrated into the device, including the most sensitive high-frequency
matching components. This eliminates the possibility of board-level
interference and degradation in performance due to the environment and
board-level designs. The built-in programmable voltage regulation (1.8V
to 3.6V) was added to eliminate the need for an external voltage
regulator, which further reduces the overall BOM cost. The device is
capable of operation using a noisy digital 1.8 to 3.6V power supply.
