Overview
The demo-board BT_HTS_RX_R2 facilitates the evaluation of the BT-STA2416C2 Bluetooth® technology wireless module in an A2DP environment. It is based on the SOUNDabout® and BLUEmagic® software of Open Interface North America, Inc and it guarantees a broad compatibility (Table 6) and a full set of certifications (Table 4, Table 5).
Figure 1. shows a block diagram of the BT_HTS_RX_R2 board. The Bluetooth® technology stream received by the RF antenna is sent to the BT-STA2416C2. This highly-integrated module is able to communicate wirelessly with BTA2DP sources such as cellular phones, BT dongles and notebook PCs.
Audio data is then fed into the STA529. This device provides the codec and a high-efficiency class-D output stage based on FFX™ technology.
The PWM output signal is then reconverted to an analog audio signal by a TS462 (or an ADA4841-2) op-amp configured to filter the PWM and supply a standard 1.5-Vpp line output.
