On transmit their outputs are combined using an external balun into the single-ended output required for the antenna. Similarly, on receive their input signals are combined internally. Both terminals present similar complex impedances that may require matching networks between them and the balun. An LC network, L4 and C17. This provides a DC bias for the BlueCore5-MM from the 1.5V rail. The BPF1 used to suppress the signal out of Bluetooth Frequency Band and enhance the EMC capacity. The DC level must be set at VDD_RADIO. 3.3 UART Ports BC05 Module UART interface provides a simple mechanism for communicating with other serial devices using the RS232 protocol. When BlueCore5Multimedia External is connected to another digital device, UART_RX and UART_TX transfer data between the two devices. The Baud rate of the UART ports:
Minimum Maximum 1200 baud (2%Error) 9600 baud (1%Error) 4Mbaud (1%Error) Baud rate 3.4 USB Ports This is a full speed (12Mbits/s) USB interface for communicating with other compatible digital devices.BC05 Module acts as a USB peripheral, responding to requests from a master host controller such as a PC. As USB is a master/slave oriented system (in common with other USB peripherals), BlueCore5Multimedia External only supports USB Slave operation. 4. Green Products and RoHS Compliance 5.
