Title: Mark Spaeth: Innovator in Clock and Data Recovery Technologies

Introduction

Mark Spaeth is a notable inventor based in Marlborough, MA (US), recognized for his contributions to the field of clock and data recovery technologies. With a total of 3 patents to his name, Spaeth has made significant advancements that enhance data signal processing.

Latest Patents

One of his latest patents is titled "Clock and Data Recovery of Sub-Rate Data." This invention involves a clock and data recovery (CDR) circuit that operates to recover a clock and sample data from both full-rate and sub-rate data signals. The CDR circuit selectively shifts one or more of the sampling clocks based on the rate of a received data signal, facilitating accurate sampling of sub-rate data signals. Additionally, a masking circuit selectively masks data output bits clocked by a selection of the sampling clocks, thereby outputting relevant sampled data.

Another significant patent is the "Modular Serializer and Deserializer." This invention includes circuits that convert a data input for a variety of applications. The serializer features an array of cells that receive a parallel data input and transfer the word, row by row, to an output buffer that generates a corresponding serial data output. The deserializer, on the other hand, includes an input buffer that receives a serial data input and transfers partial words sequentially through an array of cells. When the word fully occupies the cells, the array transmits the word as a parallel data output. A modular clock operates to clock the modular serializer and deserializer.
