A clock receiver architecture for source synchronous digital data communication, the receiver including a forwarded clock amplifier to provide the received forwarded clock signal to a plurality of delay locked loops. Each delay locked loops provides to one or more phase interpolators a set of clock signals generated from the received forwarded clock, where the relative phases of the set of clock signals are uniformly spaced. Phase interpolators interpolate between two adjacent (with respect to phase) clock signals so as to provide a clock signal to sample received data at the center of the data eye. In some embodiments, an on-die voltage regulator provides a regulated supply voltage to the delay locked loops and phase interpolators. In some embodiments, pull-up currents and pull-down currents in the phase locked loops and phase interpolators are matched across process, supply voltage, and temperature variations so that the relative phases of the clock signals are insensitive across process, supply voltage, and temperature variations. Other embodiments are described and claimed.
