Abstract: Package substrate and a method of manufacturing the same is disclosed. The package substrate includes an insulating layer having first circuit patterns embedded in a first surface of the insulating layer, and a protruded circuit pattern formed above at least one of the embedded first circuit patterns, wherein a width of the protruded circuit pattern is greater than a width of each of the embedded first circuit patterns. Accordingly, a flip chip and a wire bonding chip may be installed at the same time owing to an embedded structure of circuit pattern and a protruded structure of circuit pattern realized together on a surface where an electronic component is to be installed. Moreover, a fine circuit pattern may be formed, and a surface treatment layer may be selectively formed at desired portions without forming an additional seed layer for electroplating, thereby possibly simplifying manufacturing processes and saving manufacturing costs.

Abstract: The disclosure is directed to compensating for frequency drift in a voltage-controlled oscillator (VCO). Example methods and systems are described which may detect a signal edge associated with a transceiver, and determine whether one or more lock quality signals indicate that the VCO frequency is outside of an specified range, indicating an unacceptable amount of frequency drift. A frequency tuning setting of the VCO may be adjusted based on the one or more lock quality signals, and a determination may be made whether or not the one or more lock quality signals indicate that the VCO frequency has returned to the specified range. The adjustment of the frequency tuning setting of the VCO may be repeated until the VCO frequency returns to the specified range.
