An improved charge pump based phase locked loop where the loop filter resistor noise is reduced by about an order is presented. The graphics subsystem includes a cache unit, a tiling unit, and a screen-space pipeline coupled to the cache unit and to the tiling unit. Alternatively, the audio information may be stored in an uncompressed format and compressed immediately before delivery. The size of the assembly is configurable by bending resilient tabs of the anchor extension or the implant, using ramped surfaces, or an expanding diameter of a threadable insert. Subsequent to filtering noise from the received digital information, an approximately constant compression ratio is maintained.
