Superior Surround Made Simple

Featuring advanced technologies and filters, the FS848 High-Definition Wireless Audio IC enables home audio systems to deliver professional-quality, distortion-free audio with ease. SpeakerFinder™ technology automatically discovers and powers up speakers the moment the system is turned on. And MyZone™ technology allows the listener to position the audio sweet spot anywhere in the room. High-quality programmable digital filters enable designers to optimize speakers for specific crossover, amplifier, speaker driver, and speaker cabinet characteristics.

 

Transmitter Module

Master System Block for DTV, AVR, DVD, or Blu-ray

The FS848 can be easily integrated into many of today’s consumer electronic devices. Accepting up to eight channels of digital audio, the FS848 is completely programmable by I2C. The master controls all speaker slaves and has the ability to pass commands from the system CPU to the slaves.

 

 

Master Chip Block

In master mode, the FS848 is responsible for speaker discovery and setup, audio distribution quality, and speaker control, including volume and sleep. Audio data comes in the I2S inputs and is then encoded, forward-error corrected, and sent to the radio. Commands via I2C can be added to the audio packets by the processor.

 

 

Speaker System

Slave System Block

The FS848 slave is integrated in each speaker—the radio receives the audio data from the master and sends it to the amplifier via I2S. The master sends commands to the ultrasonic transducer for SpeakerFinder and MyZone.

 

 

Slave Chip Block

In slave mode, the FS848 processes incoming audio data by performing error correction and concealment as needed. Next, data is passed to three independent, programmable filter paths for crossover and driver equalization.
