Method and apparatus for servo data synchronization in a disc drive

摘要

A sensor chip is provided that includes a sensing element and a sigma-delta circuit that cooperate to generate sensor samples at a sensor data rate and a buffer that stores sensor samples at the sensor data rate. Although the buffer stores the samples at the sensor data rate, it is capable of providing the samples to an external circuit at a higher data rate. In one embodiment, the sensor chip is able to provide the stored sensor samples to an off-chip component at a rate set by the off-chip component.
