This paper is aimed at characterizing distinguished subclasses of $j_{qq}$-inner functions in terms of connected pairs of matrix-valued Hardy class functions. Moreover, an inverse problem for a given pair of matrix-valued Carathéodory functions is discussed.

Keywords: $j_{qq}$-inner functions, connected pairs of matrix-valued Hardy class functions, Carathéodory functions generated by a $j_{qq}$-inner function
