Mobile Phone Usage Model
The BCM4330 incorporates a number of unique features to simplify integration into mobile phone platforms.
Its flexible PCM and UART interfaces enable it to transparently connect with the existing circuits. In addition,
the TCXO and LPO inputs allow the use of existing handset features to further minimize the size, power, and
cost of the complete system.
• The PCM interface provides multiple modes of operation to support both master and slave as well as
hybrid interfacing to single or multiple external codec devices.
• The UART interface supports hardware flow control with tight integration to power control sideband
signaling to support the lowest power operation.
• The TCXO interface accommodates any of the typical reference frequencies used by cell phones.
• An analog FM receiver interface is available for legacy systems.
• FM digital interfaces can use either I2S or PCM.
• The highly linear design of the radio transceiver ensures that the device has the lowest spurious emissions
output regardless of the state of operation. It has been fully characterized in the global cellular bands.
• The transceiver design has excellent blocking (eliminating desensitization of the Bluetooth receiver) and
intermodulation performance (distortion of the transmitted signal caused by the mixing of the cellular and
Bluetooth transmissions) in the presence of a any cellular transmission (GSM®, GPRS, CDMA, WCDMA, or
iDEN). Minimal external filtering is required for integration inside the handset.
The BCM4330 is designed to provide direct interface with new and existing handset designs as shown in
Figure 3 on page 25.
