A clock data recovery (CDR) circuit that can be used for recovering data from a high-speed serial transmission using components that operate at a fraction of the data speed. The CDR consists of a phase detector, an averaging circuit and a phase interpolator. The phase detector samples each data bit at its midpoint and at its transitional region and then compares the two samples to determine whether the sampling clock, which is generated by a phase interpolator, is leading or lagging the data stream. The averaging circuit filters out the high frequency jitters in the phase detector output and then passes the filtered signals on to the phase interpolator for phase selection. The phase interpolator uses the filtered signals from the averaging circuit as a guide in the selection of an output clock phase that minimizes the phase difference between the output clock and the incoming data.

A shock absorber has a seat disk seated on a valve seat of a piston. A disk valve opens and closes a slot provided in the seat disk to extend in the circumferential direction thereof. In a low piston speed region, an orifice passage generates a damping force of orifice characteristics. In an intermediate piston speed region, the disk valve opens to generate a damping force of valve characteristics. In a high piston speed region, the seat disk opens to prevent an excessive increase in damping force. The disk valve partially opens the slot relative to the circumferential direction to gradually increase the flow path area, thereby preventing a sharp change in damping force in a transitional region from the low to intermediate piston speed region.
