9.0 Application Diagrams
The following diagrams show two application examples for
LMX9838 implementations.
Figure 1 illustrates a cable replacement application, requiring
the physical UART interface to a data device like a sensor.
The LMX9838 just waits for an incoming link and forwards
data between the data device and the bluetooth link. PG6 acts
as active link indicator and is used to enable the data transfer
from the sensor. A 32.768khz crystal may be is used to reduce
power consumption while waiting for the incoming link.

Figure 2 shows an example for the connection to a host con-
troller, which can include a simple application to control the
LMX9838. The figure also includes the connection to a PCM
codec, in case the host controller application includes an au-
dio profile. Reset, OP4 and OP5 are controlled by the host for
full control of the LMX9838 status.
Please refer to Section 17.0 Application Notes for more de-
tailed descriptions for LMX9838 designs.
