A method, apparatus, article of manufacture, and system, the method including, in some embodiments, providing a differential clock ganging structure to receive complementary differential clock signals, the differential clock ganging structure outputting clock ganging output signals, providing a source termination structure for each of the clock ganging output signals, and providing an inductance and capacitance compensation structure to receive an output of the source termination structure and to connect to a terminal interconnect for at least one of the clock ganging output signals.

Method and system for clock routing and compensation

Methods and arrangements to gang differential clock signals to attenuate pin-to-pin output skew for a clock driver are disclosed. Embodiments may comprise a pattern of conductors to interconnect output pins for differential clock signals with termination resistors. The pattern of conductors comprises a group of conductors for a positive clock (p-clock) signal and a group of conductors for a negative clock (n-clock) signal. The conductors for the p-clock signal intersect at a gang point between the output pins and pads for the termination resistors. Similarly, the conductors for the n-clock signals intersect at a gang point between the pins and the pads. In many embodiments, the distance between the pins and pads may be approximately 120 mils. In further embodiments, the distance may be longer or shorter than 120 mils. Other embodiments are disclosed and claimed.
