BT830 Hardware Integration Guide Version 0.1 (PRELIMINARY) 8.3 UART Interface This is a standard UART interface for communicating with other serial devices. CSR8811 UART interface provides a simple mechanism for communicating with other serial devices using the RS-232 protocol. The above figure shows the 4 signals that implement the UART function. When BT830 is connected to another digital device, UART_RX and UART_TX transfer data between the 2 devices.
BT830 Hardware Integration Guide Version 0.1 (PRELIMINARY) 8.4.1 PCM Interface Master/Slave When configured as the master of the PCM interface, the BT830 generates PCM_CLK and PCM_SYNC. Figure 2: PCM Interface Master Figure 3: PCM Interface Slave 8.4.2 Long Frame Sync Figure 4: Long Frame Sync (shown with 8-bit Companded Sample) Long Frame Sync is the name given to a clocking format that controls the transfer of PCM data words or samples.
BT830 Hardware Integration Guide Version 0.1 (PRELIMINARY) 8.4.3 Short Frame Sync In Short Frame Sync, the falling edge of PCM_SYNC indicates the start of the PCM word. PCM_SYNC is always one clock cycle long. Figure 5: Short Frame Sync (Shown with 16-bit Sample) As with Long Frame Sync, BT830 samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge. PCM_OUT is configurable as high impedance on the falling edge of PCM_CLK in the LSB position or on the rising edge. 8.4.
BT830 Hardware Integration Guide Version 0.1 (PRELIMINARY) 8.5 GCI Interface BT830 is compatible with the GCI, a standard synchronous 2B+D ISDN timing interface. The two 64 kbps B channels are accessed when this mode is configured. Figure 7: Multi-slot Operation The start of frame is indicated by the rising edge of PCM_SYNC and runs at 8 kHz. 8.6 Slots and Sample Formats BT830 receives and transmits on any selection of the first four slots following each sync pulse.

BT830 Hardware Integration Guide Version 0.1 (PRELIMINARY) 8.10 PCM_CLK and PCM_SYNC Generation BT830 has two methods of generating PCM_CLK and PCM_SYNC in master mode: Generating these signals by DDS from BT830internal 4MHz clock. Using this mode limits PCM_CLK to 128, 256 or 512 kHz and PCM_SYNC to 8 kHz. Generating these signals by DDS from an internal 48MHz clock, which enables a greater range of frequencies to be generated with low jitter but consumes more power.
