Bluetooth v2.1+EDR Multimedia
6 Functional Description
6.1 Overall Architecture
The ISSC IS1621N integrates an enhanced EDR Bluetooth RF & BB core, HCI controller,
Audio DSP and an ENHANCED 8051 processor with an internal mask ROM for program
memory and SRAM for data memory. An innovative interconnection structure called the
Common-Memory Architecture (CMA) is designed to provide a fast and flexible data
movement scheme between the embedded processor, Bluetooth core, and peripheral
hardware.
For audio and power management, IS1621N provide embedded audio processor, stereo
codec and some power management to reduce the external components.
6.2 Radio Frequency (RF)
6.2.1 Transmitter
The internal PA has a maximum output power of +4dBm with level control 8dB from
amplitude control. This is applied into Class2/3 radios without external RF PA. For Class1
application, the build-in level control can be used with external PA for power control
requirement.
The transmitter features IQ direct conversion to minimize the frequency drift. And it can
excess 30dB power range with temperature compensation machine.
6.2.2 Receiver
The LNA can be operated into two type modes. One type is TR-combined mode for single
port application. The other type is TR-separated mode for external PA/LNA application.
An ADC is used to sample input analogue wave for digital demodulation. Before the ADC,
a channel filter has been integrated into receiver channel to increase the anti-interference
capacity and also reduce the external component count.
For avoiding temperature variation issues, a temperature sensor with temperature
calibration is utilized into bias current and gain control of LNA, Mixers, and RF AMP.
