2 System Overview
This section provides a brief description of the system for the MC72000.
A system overview is shown in Figure 1
Figure 1. MC72000 Example Application Block Diagram
The main block is the MC72000, which will be described in depth in Section 5, “System Description.”
In addition to the MC72000, there are three other blocks:
RF signal Path
Interfaces
Reference clocks
2.1 RF Signal Path
The switch for the RX and TX, the bandpass filter, and the antenna are all found in the RF signal path.
2.2 Interfaces
There are four bi-directional interfaces and one reset that only the host can initiate.
The SSI interface is used for audio purposes.
The UART interface is used for all communication to and from the host (for example, HCI
commands).
The SPI is used for communication with the SEEPROM.
The GPIO pins are used for different configurations set by the MC72000.
2.3 Clocks/Crystals
The MC72000 has two clocks:
