SAM-200-TR

i2i

Streaming Audio Module

DESCRIPTION

The SAM-200 is an RF module for digital

streaming of CD-quality audio (48KHz, 16-bit

stereo) from simple analog inputs and outputs.

It is fully self-contained with easy-to-use

interface signals and options, to minimize time-

to-market for wireless audio applications.

Stereo line inputs and line or headphone outputs

are available. Inputs have ALC level matching

and level/impedance selection for line,

instrument, and microphone signals. Audio

outputs have mute and volume level control.

Internal voltage regulation provides flexible

management of power for embedding in existing

or new products.

Channel selection is available through direct

addressing or sequential toggling with a single

button/input. Output volume is controllable with

simple switches.

APPLICATION INFORMATION 1. Power Supply The power supply inputs are designed to run off of a variety of batteries. The level must remain above 4.0V at the rated currents or unstable operation will result. Suggested battery types: • 3.8V – 4.2V in one LiIon cell • 4.8V – 7.2V in 4 – 6 NiCd or NiMH cells • 4V – 9V in 4 – 6 Alkaline cells (0.8 – 1.0V end-of-life cell voltage assumption) 2. Audio Inputs The module is designed for three different types of audio inputs.

On the main connector, the OUT_SEL line selects between the two sets of outputs on that connector. Audio Input Selection OUT_SEL Audio Output Setting 0 Headphone-level output 1 Line-level or balanced output 4. I2C Communication The module acts as an I2C slave to support extended functionality when embedded in a product that has microprocessor control. The module maps a number of different registers accessible through the I2C communication.

know what the audio source is playing so you can identify it on the receiver.) This line is pulled up internally, and the channel advances each time it transitions to ground. The input is debounced internally to allow the use of a simple electromechanical pushbutton switch. The CH0, CH1, and CH2 lines provide for direct selection of the channel. Use these lines to select the channel from a microcontroller or when you want to hard-wire a particular channel other than the default.
