摘要: A method and apparatus for providing high speed, linear-phase interpolation. Signals from a plurality of differential pairs are weighted to produce an output clock having a selectable linear phase variation. A controller includes a pulse generator for providing a predetermined number of pulses having a predetermined phase shift and a predetermined frequency and an interpolator for processing the predetermined number of pulses having a predetermined phase shift and a predetermined frequency to generate a clock signal that is linearly adjustable between a predetermined number of output phases.

摘要: A reference token service (RTS) is disclosed. Generally, the RTS receives sensitive data items from trusted source applications associated with particular merchants. Upon receipt of a particular sensitive data item from a particular merchant, the RTS identifies one or more reference token pools corresponding to the merchant. Each reference token pool includes a plurality of reference tokens comprising formats and data structures corresponding to sensitive data items and compatible with the merchant. The RTS receives a crypto token associated with the sensitive data item which may not conform to the merchant's formatting or data requirements. The RTS associates the crypto token with a reference token corresponding to the merchant, which is provided to the merchant for sharing and retrieval of the sensitive data item amongst the merchant's various applications.
