VLSI Architectures for Asynchronous Sample-Rate Conversion

Authors: Adams, Robert; Kwan, Tom

Abstract

The theory of asynchronous sample-rate conversion is presented using both the highly-interpolated signal-processing model as well as the polyphase filter model. A novel closed-loop address-tracking system is disclosed that solves the problem of clock-edge arrival estimation while at the same time providing a low-jitter selection of the current polyphase filter for each sampling instant. The proposed signal-processing algorithm is well-suited to VLSI implementation, with only modest amounts of RAM, ROM, and digital filter hardware required.
