The present invention is a tray assembly comprising a holder, at least one tray, at least one securement device, and at least one support element. According to one aspect of the present invention, an integrated circuit device includes a semiconductor die and a first housing encapsulating the semiconductor die. Since a cosine wave generating section operates in a carrier wave frequency restoring mode and a carrier wave frequency adaptive mode, respectively, a single cosine wave ROM table can be used regardless of the respective operating modes, thereby reducing circuit complexity.
