Abstract
Forwarding points in time of a clock over a clock boundary is performed by launching the points in time into a buffer, such as a FIFO, in the first clock domain. The oldest point in time is fed into a FIFO or delay line in the other clock domain, which FIFO or delay line comprises a plurality of received points in time, which are shifted through the FIFO or delay line over time. An estimate of a point in time in the second clock domain is derived from a plurality of the points in time in the delay line/FIFO, such as from a mean value thereof. This point in time may be compensated for a known delay in order for this determined point in time to be identical to or close to an actual point in time of the first clock in the first clock domain.
