SYSCLK and SYSCLK# DC Characteristics
Table 11 shows the DC characteristics of the SYSCLK and
SYSCLK# differential clocks. The SYSCLK signal represents
CLKIN and RSTCLK tied together while the SYSCLK# signal
represents CLKIN# and RSTCLK# tied together. For more
information about SYSCLK and SYSCLK#, see “SYSCLK and
Figure 10 shows the DC characteristics of the SYSCLK and
SYSCLK# signals.

The following processor inputs have twice the listed capacitance because they connect to two input pads—SYSCLK and SYSCLK#.
SYSCLK connects to CLKIN/RSTCLK. SYSCLK# connects to CLKIN#/RSTCLK#.
