1. General description
The Ensation Base, SAA8200HL, is part of the integrated wireless audio system chip set
offered by Philips. This chip set enables the development of low cost wireless digital audio
systems. The chip set contains:
• An integrated wireless audio baseband chip (SAA8200HL)
• An integrated wireless audio radio chip (TEA7000).

Integrating a wireless audio link in a home theatre system to remove part of the wiring is a
logical application of wireless audio transmission. A very important property of this
wireless audio system is the low end-to-end (audio-in at transmit side to audio-out at
receive side) system latency, which is below 20 ms.
A second important property is the robustness and reliability of the wireless audio link, the
SAA8200HL which is handling the signal processing and the system control enables this.
Furthermore, the SAA8200HL provides the flexibility to allow designers to make trade-offs
between air bit-rate, number of transported audio channels, audio formats, audio coding
bit-rates, range, number of receiving-slaves and more.
Due to its low power consuming design, the SAA8200HL enables battery powered
applications. The SAA8200HL does this all with a minimum of external components due to
its high level of integration.
