Synchronous data system and method for providing phase-aligned output data

摘要

Embodiments of a synchronous data system and method for generating phase-aligned output data are generally described herein. In some embodiments, the synchronous data system includes a plurality of transmitter-receiver (TX-RX) pairs, each associated with a delay-locked loop (DLL) and arranged to generate corresponding output data stream based on a high-speed clock of the associated TX-RX pair. The DLL associated with each TX-RX pair is a phase-shifter DLL that includes an adjustable phase shifter arranged to minimize the phase error between the system clock and the module clock to edge-align the high-speed clocks of each TX-RX pair.

1. A synchronous data system comprising:
a plurality of transmitter-receiver (TX-RX) pairs, each TX-RX pair associated with a delay-locked loop (DLL) and arranged to generate corresponding output data based on a high-speed clock of an associated TX-RX pair, wherein the DLL associated with each TX-RX pair is arranged to synchronize a module clock of the TX-RX pair to a system clock so that the output data of the TX-RX pairs is phase-aligned, and wherein the DLL is a phase-shifter DLL that includes an adjustable phase shifter arranged to minimize a phase error between the system clock and the module clock to edge-align the high-speed clock of each TX-RX pair.
