Latest Patents

Hsu's latest patents include a "High frequency loss of signal detector" and a "Phase lock loop with cycle drop and add circuitry." The high frequency loss of signal detector is designed for Gb/s telecommunication applications. This invention measures the bit error rate (BER) of incoming data by comparing the phase of the clock signal extracted from the data with a delayed version of the same data. The results are averaged over time to determine the BER, which is then compared to a predetermined threshold to detect any loss-of-signal conditions. Additionally, the invention optimizes the delay of incoming data to minimize capacitive loading on the data and clock lines.

The phase lock loop with cycle drop and add circuitry allows for adjustments in the frequency of a clock signal. This innovation enables a transmitter to modify its data transmission rate according to the clock signal, accommodating various data transmission protocols. The phase locked loop can add or drop cycles from the input clock signal based on signals from a receiver, which indicate the transmission rate of the incoming data. This flexibility allows the transmitter to either decrease or increase its data transmission rate in response to changes in the clock signal frequency.
