ABSTRACT:
A data separator which extracts data embedded in a read signal includes a delay circuit that is controlled by a frequency synthesizer. The frequency synthesizer provides a write clock during write operations. A controlled oscillator included in the frequency synthesizer resides on a common integrated circuit with the delay circuit. Because component fabrication variations tend to track on a common integrated circuit, the frequency synthesizer compensates for fabrication variations in the delay circuit, thereby producing an accurate delay interval.
