3.7.1 Bluetooth (BCM2070)
Bluetooth block of LG-C320 consists of a BCM2070 chip-set, an external crystal oscillator(26MHz), and a
Bluetooth chip antenna (2.4GHz). QSC6270_3G disable, which is main HW solution of LG-C320 Model, doesn’t
include BT baseband core. Instead, Bluetooth chipset, BCM2070, contains stand-alone baseband processor
(V2.1+EDR) as well as BT RF block. An external crystal oscillator (26MHz) is used to provide reference
frequency to BCM2070.
Figure 3.7 shows the Bluetooth system architecture in the LG-C320.
