摘要:
An electronic device is described. The electronic device includes a first integrated circuit (IC) and a second integrated circuit (IC). The electronic device also includes a multiplexer configured to multiplex a parallel data signal into a serial data signal, and a transmitter configured to transmit the serial data signal from the first IC to the second IC. The electronic device further includes a receiver configured to receive the serial data signal. The receiver includes a clamp circuit configured to clamp the voltage swing of an analog node within a determined range. The clamp also helps to extend the bandwidth of the receiver.
摘要:
A transceiver interface for data transfer between two integrated circuits (ICs or 'chips') utilizes a current mode technique rather than conventional voltage mode differential signaling techniques. A current pulse is injected into one of two transmission wires based on a signal value to be transmitted (e.g., logic '0' or '1') by a driver on a transmitting chip. The current pulse is received as a differential current signal at a receive block in a receiving chip. The differential current signal is converted to a low swing differential voltage signal by current comparators. The differential voltage signal may be detected by an op-amp receiver which outputs the appropriate signal value.
