Title: Jim Knittel: Innovator in Digital Data Communication
Introduction
Jim Knittel is a notable inventor based in Campbell, California. He has made significant contributions to the field of digital data communication, holding 2 patents that showcase his innovative approach to synchronizing communication systems.
Latest Patents
One of Jim's latest patents is an apparatus and method for synchronizing an SCDMA upstream or any other type upstream to an MCNS downstream or any other type downstream with a different clock rate than the upstream. This bidirectional digital data communication system generates phase coherent upstream clock and carrier signals from a recovered downstream clock generated from a master clock in a central unit. The preferred species uses any downstream clock rate and generates a phase coherent upstream clock as long as the two clock rates can be related by the ratio M/N, where M and N are integers. One embodiment utilizes an MCNS downstream and an SCDMA upstream, employing MNCN timestamp messages in the downstream to estimate the RU frame offset prior to establishing frame alignment through a ranging process. The use of timestamp messages to estimate the offset is enhanced by a low jitter method for inserting timestamp messages, avoiding straddling of MPEG packet headers with the sync message. Clock slip is detected by counting upstream clock cycles over a predetermined downstream clock interval, and the RU transmitter is shut down if slip is detected to prevent ISI interference from misaligned codes. Additionally, an SCDMA transmitter for the minislot environment of 802.14 and MCNS is disclosed, along with a receiver for the minislot environment using TDMA or SCDMA demultiplexing.
