AB1120
Bluetooth 3.0 Single Chip for
HID Applications
A direct-up conversion architecture is used in the transmitter part. The output power level
at TX part is +6dBm for the basic data rate, with 20dB VGA gain tuning range.
A fractional-N synthesizer is implemented in AB1120 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. External clock signal can
also be fed into AB1120 instead of the 26MHz crystal clock signal.
2.2 Baseband Processor
The Baseband Processor of AB1120 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, scatter-net operation, etc.
2.3 Serial Communication Interface
Several Serial Communication Interfaces including USB, UART and SPI are supported in
AB1120. An I2C interface is implemented for EEPROM access.
2.4 I/O Ports
The total number of I/O pins of AB1120 is 18 pins, including 6 pins dedicated for input
and 1 pin (PIO29) dedicated for EEPROM Write Protection. Other 11 I/O pins are
programmable and support both input and output. A 3-axis detection is supported for
external button control (i.e. PIO4/PIO5 are dedicated to ZA/ZB control in mouse
application). Two LED drivers with faders for blue/red LEDs are also included.

6.2 Modulator and Demodulator
The modulator can generate GFSK, DQPSK and D8PSK signals according to which data
rate is adopted in the frame data. The demodulator can convert the received data signal
to digitized data bit format according to the modulation type indicated in the header
region.
6.3 Bluetooth Timing Processing Unit
A Bluetooth Timing Processing Unit (TPU) is embedded in the Baseband processing unit.
TPU is in charge of generating RF timing control signals to the RF radio part, such as TX
enabling signals and RX enabling signals.
