A multi-media device interface () couples a multi-media device () to a portable electronic device (). Multi-media and other information can be loaded into the portable electronic device () from the multi-media device () or stored in the multi-media device () from the portable electronic device (). The multi-media device interface () queues commands to the multi-media device () from the portable electronic device () while the multi-media device () completes a previously-issued command.

Command queuing for multimedia storage devices

A lock loop circuit () includes a precharge circuit (), an oscillator circuit (), and a calibration circuit (). The calibration circuit includes at least one register (). The precharge circuit provides a precharge signal (). The oscillator circuit provides an output frequency signal () in response to a steering signal () that is based on the precharge signal. The calibration circuit, prior to the lock loop circuit entering a disabled mode of operation, determines a calibration value () for the precharge circuit based on the precharge signal and the steering signal. The calibration circuit stores the calibration value as a digital calibration value () in the register.

Automatic calibration lock loop circuit and method having improved lock time

A lock loop circuit () includes a floating ground loop filter circuit () and a precharge circuit (). The floating ground loop filter circuit includes at least one capacitive element (). The floating ground loop filter circuit provides a steering signal () for a controllable oscillator circuit () in response to a precharge signal (). The precharge circuit provides the precharge signal in response to lock loop enable information (). The precharge circuit controls the floating ground loop filter to bypass the at least one capacitive element for a period of time () in response to the lock loop enable information.
