GRCon21 - A new Linux kernel subsystem for JESD204 RF Transceiver Systems

Presented by Michael Hennerich at GNU Radio Conference 2021 Title: A new Linux kernel subsystem for JESD204 multichannel RF Transceiver Systems Author: First Name: Michael Last Name: Hennerich Organization: Analog Devices GmbH Country: Germany Email: [email protected] Abstract: Many applications need multiple channels of phase and frequency synchronization and coherency. Applications like Direction of Arrival (DOA) accuracy is directly related to the number of channels and the synchronization between these channels. However, synchronizing multiple high-speed RF transceiver systems is a challenging task from both hardware and software point of view. In most cases these systems need to scale both vertically and horizontally. This presentation will introduce a new yet to be mainlined JESD204 Linux kernel subsystem, which greatly simplifies configuration, bring-up and synchronization of multi topology converter systems and clocking trees. We will cover the basic architecture and concepts, the stack-up and components, how they typically interact with each other, the type of (inter)dependencies that exist and finally how easy it is to utilize, compose and scale such a system. About: Michael is Open Source Engineering Manager at Analog Devices GmbH in Munich, and also passionate and licensed HAM Radio Amateur. He first talked about Embedded Linux for DSPs on the Embedded Systems Conference Silicon Valley back in 2006, since then Michael is an active Linux kernel developer and open source contributor. https://events.gnuradio.org/event/8/
