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, SAA8200HL 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. It does this all with a minimum of external components due to its high level of integration.
Together with the TEA7000, the SAA8200HL can be used to implement an indoor wireless link for audio applications (system specific). Together with an AV-compliant Bluetooth radio module, the SAA8200HL can be used to implement a Bluetooth wireless audio functionality.
The SAA8200HL enables a low power, low cost two-chip solution with a maximum amount of functions integrated on the device, taking into account strict time-to-market constraints.
