\section{Electrical Specifications}
All specifications are in $0\degree C \leq T_A \leq 70\degree C$ unless otherwise noted.
Pulse width distortion \& peak jitters are based on the isolator IC (SI8651BB-B-IS1), other specifications are based on the bus transceivers IC (SN74BCT25245DW).
Specifications are based on the bus transceivers IC (SN74BCT25245DW\footnote{\label{transceiver}https://www.ti.com/lit/ds/symlink/sn74bct25245.pdf})
and the isolator IC (SI8651BB-B-IS1\footnote{\label{isolator}https://www.skyworksinc.com/-/media/Skyworks/SL/documents/public/data-sheets/si865x-datasheet.pdf}).
