Latest Patents

One of Lopez's latest patents is titled "System and method for using a network timing reference circuit as a phase detector in a synchronization loop." This invention improves system clock synchronization in digital transceivers by generating a phase error correction signal without the need for additional transmitted information or external circuitry. The system enables a transceiver to achieve timing and synchronization lock to a master clock, such as a T1 or E1 clock, by utilizing a higher-frequency replica of the local clock signal. The network timing reference unit plays a crucial role in generating phase error samples that can be manipulated for effective clock synchronization.

Another notable patent is focused on "Alternative configurations for an ADSL system operating in a time duplex noise environment." This invention provides various configurations to limit crosstalk in broadband networks. It introduces a trial bitmap profile configuration to maximize the bit rate for information transmission, regardless of the network topology. By deriving a composite signal-to-noise ratio, the system determines the maximum bit rate for data transfer, ensuring efficient communication even in challenging noise environments.
