BCM88335 Data Sheet  
Bluetooth Radio  
Scatternet operation with up to four active piconets with background scan and support for scatter mode  
High-speed HCI UART transport support with low-power out-of-band BT_DEV_WAKE and  
BT_HOST_WAKE signaling (see “Host Controller Power Management” on page 36)  
Channel quality driven data rate and packet type selection  
Standard Bluetooth test modes  
Extended radio and production test mode features  
Full support for power savings modes  
– Bluetooth clock request  
– Bluetooth standard sniff  
– Deep-sleep modes and software regulator shutdown  
TCXO input and autodetection of all standard handset clock frequencies. Also supports a low-power  
crystal, which can be used during power save mode for better timing accuracy.  
Bluetooth Radio  
The BCM88335 has an integrated radio transceiver that has been optimized for use in 2.4 GHz Bluetooth  
wireless systems. It has been designed to provide low-power, low-cost, robust communications for applications  
operating in the globally available 2.4 GHz unlicensed ISM band. It is fully compliant with the Bluetooth Radio  
Specification and EDR specification and meets or exceeds the requirements to provide the highest  
communication link quality.  
Transmitter  
The BCM88335 features a fully integrated zero-IF transmitter. The baseband transmit data is GFSK-modulated  
in the modem block and upconverted to the 2.4 GHz ISM band in the transmitter path. The transmitter path  
performs signal filtering, I/Q upconversion, output power amplification, and RF filtering. The transmitter path also  
incorporates /4-DQPSK and 8-DPSK modulations for 2 Mbps and 3 Mbps EDR support, respectively. The  
transmitter section is compatible to the Bluetooth Low Energy specification. The transmitter PA bias can also be  
adjusted to provide Bluetooth Class 1 or Class 2 operation.  
Digital Modulator  
The digital modulator performs the data modulation and filtering required for the GFSK, /4-DQPSK, and  
8-DPSK signal. The fully digital modulator minimizes any frequency drift or anomalies in the modulation  
characteristics of the transmitted signal and is much more stable than direct VCO modulation schemes.  
Digital Demodulator and Bit Synchronizer  
The digital demodulator and bit synchronizer take the low-IF received signal and perform an optimal frequency  
tracking and bit-synchronization algorithm.
