The STLC2690 combines Bluetooth and FM transceiver functionality on a single chip and is fully optimized for mobile applications such as mobile phones, smart phones, PDAs and portable media players. The required board space has been minimized, power consumption levels are targeted for battery powered devices and the integration allows a cost effective solution. Amongst others the reduction of external components enables manufacturers to easily and fast integrate the STLC2690 on their product to enable a short time to market. Compared to its successful predecessor, the STLC2593, the STLC2690 is a system on chip device, it adds an FM transmitter, an audio processor and A2DP encapsulation and further optimizes in terms of RF performance and cost.

stlc2690結合在一個單芯片藍牙和FM收發(fā)功能，全面優(yōu)化的移動應用如手機、智能手機、PDA和便攜式媒體播放器。所需的電路板空間已被最小化，功率消耗水平是針對電池供電設備和集成允許一個成本有效的解決方案。其他外部元件的減少使制造商能夠輕松，快速融入stlc2690對他們的產品，使短時間內市場。相比其前身的成功，stlc2593，的stlc2690是芯片裝置系統(tǒng)，它增加了一個FM發(fā)射器，音頻處理器和射頻性能和成本方面的A2DP封裝和進一步優(yōu)化。
