BCM20730 Data Sheet
ADC Port
Adaptive Frequency Hopping
The BCM20730 gathers link quality statistics on a channel-by-channel basis to facilitate channel assessment
and channel map selection. The link quality is determined by using both RF and baseband signal processing to
provide a more accurate frequency hop map.
Bluetooth Version 3.0 Features
The BCM20730 supports Bluetooth 3.0, including the following options:
• Enhanced Power Control
• Unicast Connectionless Data
• HCI Read Encryption Key Size command
The BCM20730 also supports the following Bluetooth version 2.1 features:
• Extended Inquiry Response
• Sniff Subrating
• Encryption Pause and Resume
• Secure Simple Pairing
• Link Supervision Timeout Changed Event
• Erroneous Data Reporting
• Non-Automatically-Flushable Packet Boundary Flag
• Security Mode 4
Test Mode Support
The BCM20730 fully supports Bluetooth Test mode, as described in Part 1 of the Bluetooth 3.0 specification.
This includes the transmitter tests, normal and delayed loopback tests, and the reduced hopping sequence.
In addition to the standard Bluetooth Test mode, the device supports enhanced testing features to simplify RF
debugging and qualification as well as type-approval testing.
ADC Port
The BCM20730 contains a 16-bit ADC (effective number of bits is 10).
Additionally:
• There are 28 analog input channels in the 64-pin package, 12 analog input channels in the 40-pin package,
and 9 analog input channels in the 32-pin package. All channels are multiplexed on various GPIOs.
• The conversion time is 10 μs.
• There is a built-in reference with supply- or band-gap based reference modes.
• The maximum conversion rate is 187 kHz.
• There is a rail-to-rail input swing.
