CY920

5.0 BLUETOOTH SPECIFICATIONS

The Bluetooth (BT) subsystem included in the CY920

module shares the antenna connections with the Wi-Fi

subsystem. Dedicated control signals between the

DM920 module and the BT controller perform Packet

Traffic Arbitration (PTA) to optimise co-existence

between the Wi-Fi and BT subsystems. A high-speed

UART interface is used to send data from the BT

controller to the DM920 SoC for further processing.

5.1 Features

The following are the Bluetooth features:

• Compliant with Bluetooth v2.1 + EDR

specification

• SBC and AAC codec

• A2DP and AVRCP profiles

• WLAN and Bluetooth co-existence using PTA and

AFH

• Utilises single antenna, shared with Wi-Fi

• Operating band: 2.4 GHz ISM band

• Output power Class 2 (+4 dBm)

• Low power consumption

5.2 Bluetooth Radio Characteristics

Table 5-1 provides Rx and Tx characteristics of the

Bluetooth radio.
