5 Timestamp interpolator

The timestamp interpolator increases the resolution of a timestamp.

The interpolator shifts the input timestamp left by 8 bits, and uses the extra low-order bits to provide a more accurate timestamp value. The greater accuracy is achieved by monitoring changes to the input timestamp value over time to predict how fast it counts.

The following figure shows the external connections on the Timestamp interpolator.
