3.4.3
The IPAC-X 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
synchronized to the S-interface.
In power down mode the C768 output is disabled (low signal).
