<p>A media player with low time base jitter is provided, and which includes a central controller for decoding media data, a storage module which connects with the central controller for storing the media data, a digital-to-analog conversion module for converting the media data decoded by the central controller to an analog signal, and an externally-connected clock module which connects with the central controller for providing clock signal for the central controller. Because the externally- connected clock module is used, and the clock module, in itself, employs the active crystal oscillator with low oscillation error and uses the programmable logic device to process the lock, the clock signal provided by the externally-connected clock module has low error, and the time base jitter is low.</p> |
