摘要： A positive differential signal trace and a negative differential signal trace are formed on different layers of a printed circuit board. A first ground trace is formed on the layer on which the positive differential signal trace is formed, and a second ground trace is formed on the layer on which the negative differential signal trace is formed. An insulation layer is positioned between the two layers and has a predetermined thickness. A differential mode impedance and a common mode impedance of differential signals are dependent on the predetermined thickness of the insulation layer, width and thickness of each differential signal trace, and a space between each differential signal trace and the corresponding ground trace formed on the same layer.

摘要： A Bluetooth audio chip with multiple input/output sources is implemented on a monolithic integrated circuit. The Bluetooth audio chip includes a Bluetooth Baseband/RF module, an encode/decode module, a stereo ADC/DAC codec module, a USB module, a UART module, and a flash memory. Each one of the modules receives/transmits one kind of audio source, thus the Bluetooth audio chip has deeply embedded with multiple input/output sources. The Bluetooth audio chip is used in a diversity of applications to reduce the cost and time comparing to one purpose chip for just only one specific application.
