BCM43455 Preliminary Data Sheet
Mobile Phone Usage Model
•
IEEE 802.11 Extensions:
– IEEE 802.11e QoS Enhancements (as per the WMM specification is already supported)
– IEEE 802.11h 5 GHz Extensions
– IEEE 802.11i MAC Enhancements
– IEEE 802.11k Radio Resource Measurement
Mobile Phone Usage Model
The BCM43455 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 crystal oscillator interface accommodates any of the typical reference frequencies used by cell phones.
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 and intermodulation performance in the presence of a
cellular transmission (LTE, GSM, GPRS, CDMA, WCDMA, or iDEN).
The BCM43455 is designed to directly interface with new and existing handset designs.
