In Hicom 390.1 systems, control is generated by the common control via the IOCC board.

In Hicom 391.1 systems, the CCD board is used to expand the clock distribution field.

The CCG board controls the CCD board, which supplies 22 clock repeaters with the reference clock signal (CKAREF) and with the frame mark bit synchronization signal (FMBREF).
