Sampled-data techniques are the most practical means of obtaining the necessary signal processing functions for timing recovery in the VLSI implementation of a digital subscriber loop transceiver. The sampled-data timing recovery techniques described in this paper are applicable to both echo cancellation ...

processing loops back to junction 132 and hence inquiry 134 to determine whether the arrival level of the current point Y is less than the arrival level at the subject point X. Obviously, the particular points (and, therefore, the values) for point X, point Y and point Z change as GetAr...
Timing and carrier synchronization is a fundamental requirement for any wireless communication system to work properly. Timing synchronization is the process by which a receiver node determines the correct instants of time at which to sample the incoming
In this chapter, we give an overview on timing models which provide an abstract representation of the timing behavior for a given software. These models can be driven by a functional simulation based on the simulated control flow. As the timing model itself can reach a level of accuracy that...

The FOM is designed to evaluate the jitter performance of Phase-Locked Loops (PLLs) in the context of power dissipation and operating speed. This FOM can also be used to compare low-jitter clock receivers. The figure of merit is defined as: 𝐹𝑂𝑀=10𝑙𝑜𝑔[(𝜎𝑡1 𝑝𝑠...
If the results are not acceptable, then flow loops back (“No” 105N) to repeat some portion of the place and route operations. In some usage scenarios (not illustrated) one or more modifications to any combination of the design and the technology may be made before repeating some of the...
