generator (CDCM61004RHBT). Users designing SATA applications must use a 100MHz reference
clock on the SATA_REFCLK signal which would lead to the same clock frequency applied to the
PLL_CLKIN signal. At this stage any arbitrary changes to the PLL_CLKIN is not allowed as users
can only change the PLL_CLKIN clock frequency if the SATA interface is not in use. The I/O
standard for the three clock generators is set as LVDS which is non-configurable.
An overall block diagram of the external clock generator is shown below in
