LTE OPEN EVB provides a Micro-USB interface J0601 for connection with a host device. The USB data

lines USB_DP and USB_DM are connected directly to the LTE-QuecOpen modules. The USB_VBUS line

can be used for USB connection detection and EVB power supply.

4.5. Audio Interfaces

LTE OPEN EVB provides one digital audio codec board interface (PCM) J0804 and three analog audio

interfaces J0801, J0802 and J0805.

4.5.1. Digital Audio Codec Board Interface (J0804)

LTE OPEN EVB supports two different kinds of external digital audio codecs named ALC5616 and

TLV320AIC3104. The codec circuit is assembled on an independent small board which can be

interconnected with EVB via the BTB connector J0501.

Customers can select different codecs according to their own application demands, and also can use AT

command to switch between codecs. Two examples are provided below. For more details, please refer to

document [5]



AT+QDAI=3

: switch codec from TLV320AIC3104 to ALC5616



AT+QDAI=5

: switch codec from ALC5616 to TLV320AIC3104

The following figure show a reference design for the connection between digital audio codec boards and

the EVB.
