Abstract: A system of the present invention uses small swing differential source synchronous voltage and timing reference (SSVTR and /SSVTR) signals to compare single-ended signals of the same slew rate generated at the same time from the same integrated circuit for high frequency signaling. The SSVTR and /SSVTR signals toggle every time the valid signals are driven by the transmitting integrated circuit. Each signal receiver includes two comparators, one for comparing the signal against SSVTR and the other for comparing the signal against /SSVTR. A present signal binary value determines which comparator is coupled to the receiver output, optionally by using exclusive-OR logic with SSVTR and /SSVTR. The coupled comparator in the receiver detects whether change in signal binary value occurred or not until SSVTR and /SSVTR have changed their binary value. The same comparator is coupled if the signal transitions. The comparator is de-coupled if no transition occurs.

Abstract: In one embodiment, a system for deskewing signals on parallel bus channels includes several parallel channels that carry several data input signals and a pair of complementary voltage and timing reference (VTR) signals. The system also includes several receivers, with each receiver coupled to receive a data input signal and the pair of complementary VTR signals. The output of each receiver is based in part on a comparison of the received data input signal with the pair of complementary VTR signals. In one embodiment, a pair of VTR signals is selected from several pairs of VTR signals to widen the skew band on each channel. In one embodiment, each channel is skewed using a programmable delay circuit having a delay value based on the alignment of a data input signal relative to a pair of complementary VTR signals.

Abstract: A system enables the capture of incoming signals from different components when the skew between the different components is higher than the signal rate. The system comprises a first port for serially receiving a first signal at a signal rate from a first component; a second port for serially receiving a second signal at the signal rate from a second component; a first serial-to-parallel conversion circuit for performing serial-to-n-bit-parallel conversion of the first signal, n being greater than one; and a second serial-to-parallel conversion circuit for performing serial-to-n-bit parallel conversion of the second signal.
