Bluetooth 3.0 Single Chip for
Keyboard Applications
2 Description
AB1107 is a single-chip IC for wireless Bluetooth Keyboard applications, which supports
Bluetooth system version 3.0 features including AFH function. It supports sniff sub-rating
for longer battery life & faster re-connect. Bluetooth 3.0 simple-pairing mechanism is also
implemented. It complies with RF transceiver, baseband processor, PMU, switching
regulator, Boost regulator and Li-ion battery charger. Several Serial Communication
Interfaces including UART, I2C and SPI are supported.

2.1 Radio Transceiver
A common RF terminal is shared by the TX/RX paths of AB1107 with embedded TX/RX
switch. Only few matching components are required in the RF port.
The receiver sensitivity is –88dBm at basic data rate. The output power level at TX part is
+6dBm for the basic data rate, with 20dB VGA gain tuning range.

AB1107
Bluetooth 3.0 Single Chip for
Keyboard Applications
A fractional-N synthesizer is implemented in AB1107 with internal loop filters such that no
external components are required.
An internal crystal oscillator is integrated such that only an external 26MHz crystal is
required. An internal 32.768KHz slow clock is also generated.
2.2 Baseband Processor
The Baseband Processor of AB1107 supports Bluetooth 3.0 specifications including AFH.
A digital data processing unit is in charge of the GFSK, DQPSK and D8PSK
modulation/demodulation, channel filtering, error detection/correction, and burst
framing.
A MCU-based Link Controller is implemented for the whole baseband control functions. A
firmware is in charge of the Link Management Protocols, Profiles and MMI. Several
hardware accelerators are implemented to support the baseband processing such as
encryption.
2.3 Serial Communication Interface
Several Serial Communication Interfaces including UART and SPI are supported in AB1107.
A I2C interface is implemented for EEPROM access.
2.4 I/O Ports
The total number of I/O pins of AB1107 is 29 pins, including 4 pins dedicated for input
only. Other 25 I/O pins are programmable and support both input and output. Up to 16
pins could be programmed as input simultaneously, for example a device with 16 buttons.
A 3-axis detection is supported for external button control. Two LED drivers with faders
for blue/red LEDs are also included.
