Functional Description
2.9
Oscillator Circuit
The IPAC derives its system clocks from an external clock connected to XTAL1 (while
XTAL2 is not connected) or from a 7.68 MHz crystal connected across XTAL1 and
XTAL2.
At pin C768 a buffered 7.68 MHz output clock is provided to drive further devices, which
is suitable in multiline applications for example (see figure 77). This clock is not
synchronized to the S-interface.
