    • A system is disclosed including an electronic device having a case housing an operative portion, such as a sound system, CD Player, or the like. A bay is formed in the case and includes a communication channel interface electrically coupled to the operative portion. The system further includes a portable computer, such as a personal digital assistant (PDA). The portable computer is sized to fit within the bay having a communication channel thereof in data communication with the communication channel interface. The portable computer stores applications including one or more control applications programmed to generate control signals in response to user inputs. Applications may display an interface on a touch screen and receive user inputs therefrom. The control signals are transmitted to the operative portion which responds to the control signals by playing music, adjusting a volume level, and the like.

    • A translator circuit for providing symmetrical switching delays for use with a power line for a differential amplifier having a first signal line and a complementary second signal line, the translator circuit including: a first voltage clamp coupled to the first signal line and to the power line for limiting a voltage differential between the power line and the first signal line; and a second voltage clamp coupled to the power line and the second signal line for limiting a voltage differential between the power line and the second signal line. The translator circuit provides reduced sensitivity to variations in process parameters, power supply voltages, temperature and manufacturing tolerances. The translator circuit also provides symmetrical tracking between the rise to rise and the fall to fall delays of an emitter coupled logic to complementary metal-oxide semiconductor translator circuit.
