摘要： Disclosed herein are a data transmission circuit and a data communication device that transmit data using an Alternating Current (AC)-coupled transmission line. The data transmission circuit includes a data transmission unit for transmitting data via a transmission line having a single AC-coupled line or a plurality of AC-coupled lines. When transmitting data, the data transmission unit transmits the data via the transmission line by sequentially setting a first electric potential corresponding to the data and a second electric potential different from the first electric potential. When transitioning from data transmission mode to an idle state, the data transmission unit sets an intermediate electric potential between the first electric potential and the second electric potential.

摘要： A DC-balanced signal is imposed on the input of a transmission line. Prior to imposing the DC-balanced signal, the input of the transmission line is held at an intermediate DC level that intermediate between the maximum and minimum DC levels of the DC-balanced signal. Alternatively, a compensating pulse is additionally imposed on the input of the transmission line. The compensating pulse compensates for a change in the DC level at the output of the transmission line caused by the imposing of the DC-balanced signal on the input of the transmission line.

摘要： The DC offset of a differential signal can be changed by differentially shifting the DC offset of each of its signals. Techniques are presented for changing, in a controlled way, the DC offset of a differential signal as received by a receiver of a data transmission system. Several classes of example embodiments, utilizing digitally controllable voltage or current sources, are presented. The classes differ based upon such factors as coupling capacitor arrangement and use of termination resistors. Specific embodiments, within each class, differ based upon such factors as whether voltage or current sources are used and the characteristics of such sources. Once the DC offset of a differential signal has been changed, the effect of such change on a performance metric can be measured. Example applications include the ability to determine a differential signal level that results in BER having a particular level and determination of differential signal margin.

摘要： When communicating data between different voltage and frequency domains, for example chiplets, in an integrated circuit, the data signals can be formatted to compensate for propagation delays and different operating frequencies between the domains, and the signaling voltage level of the formatted data signals can then be changed from the operating voltage of the transmitting domain to the operating voltage of the receiving domain so that the formatted and changed data signals can be transmitted. As such, voltage crossings are combined with frequency crossings, which can have the effect of hiding the voltage shifting within the propagation delays.

摘要： An integrated circuit containing a communication channel is described. This communication channel includes: a transmit circuit configured to transmit signals; a link coupled to an output of the transmit circuit; a receive circuit coupled to the link; and a clamping circuit coupled to the link. Note that the transmit circuit is capacitively coupled to the receive circuit via the link. Furthermore, the clamping circuit is configured to compensate for leakage current on the link by maintaining a voltage on the link corresponding to a logical “1” or a logical “0.” This voltage is based on a history of the transmitted signals.
