BT800 Hardware Integration Guide Version 0.2 Figure 3: PCM Interface Slave 9.4.2 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. In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the PCM word. When BT800 is configured as PCM master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is 8 bits long.
BT800 Hardware Integration Guide Version 0.2 As with Long Frame Sync, BT800 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. 9.4.4 Multi-slot Operation More than 1 SCO connection over the PCM interface is supported using multiple slots. Up to 3 SCO connections are carried over any of the first 4 slots.

BT800 Hardware Integration Guide Version 0.2 9.10 PCM_CLK and PCM_SYNC Generation BT800 has 2 methods of generating PCM_CLK and PCM_SYNC in master mode: Generating these signals by DDS from BT800internal 4MHz clock. Using this mode limits PCM_CLK to 128, 256 or 512kHz and PCM_SYNC to 8kHz. 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.

BT800 Hardware Integration Guide Version 0.2 13 IMPLEMENTATION NOTE 13.1 PCB Layout on Host PCB Checklist (for PCB): MUST locate BT800/BT810 module close to the edge of PCB. Use solid GND plane on inner layer (for best EMC and RF performance). Place GND vias close to module GND pads as possible Route traces to avoid noise being picked up on VCC supply. Antenna Keep-out area: - Ensure there is no copper in the antenna keep-out area on any layers of the host PCB.
