Multiline PC-Adapter
Up to three S-interfaces can be combined using one IOM interface (figure 8). All three
IPACs are configured for LT-T mode in different channels. The SCLK output is used for
DCL clock and the FSC clock is generated by one device. Only one 7.68 MHz crystal is
required for the three IPACs as they provide a buffered output clock derived from the
XTAL1 clock input.
