Functional Description

2.2

IOM-2 Interface

The IOM-2 Interface consists of two data lines and two clock lines. DU (data upstream)

carries data from the SICOFI-4 to a master device. This master device performs the

interface between the PCM-backplane, the µ-controller and up to 24 SICOFI-4’s. DD

(data downstream) carries data from the master device to the SICOFI-4. A frame

synchronization clock signal (8 kHz, FSC) as well as a data clock signal (2048 kHz or

4096 kHz DCL) has to be supplied to the SICOFI-4. The SICOFI-4 handles data as

described in the IOM-2 specification for analog devices.
