Substrate module having an embedded phase-locked loop, integerated system using the same, and fabricating method thereof

摘要

A substrate module having an embedded phase-locked loop is cooperated with at least one function unit mounted thereon for forming an integrated system. The substrate module includes a base, a multi-layer structure, a built-in circuit unit, and an external circuit unit. The built-in circuit unit is integrated inside the multi-layer structure and the multi-layer structure is formed in the base. The external circuit unit is mounted on the upper surface of the base and is electrically coupled to the built-in circuit unit for jointly forming a phase-locked loop, so as to cooperate with the function unit.
