Clock input. CLK provides the clock signal to be distributed by the CSP2510C clock driver. CLK is used to provide the reference signal
to the integrated PLL that generates the clock output signals. CLK must have a fixed frequency and fixed phase for the PLL to obtain phase
lock. Once the circuit is powered up and a valid CLK signal is applied, a stabilization time is required for the PLL to phase lock the feedback
signal to its reference signal.
Feedback input. FBIN provides the feedback signal to the internal PLL. FBIN must be hard-wired to FBOUT to complete the PLL. The
integrated PLL synchronizes CLK and FBIN so that there is nominally zero phase error between CLK and FBIN.
Output bank enable. G is the output enable for outputs Y(0:9). When G is low, outputs Y(0:9) are disabled to a logic-low state. When
G is high, all outputs Y(0:9) are enabled and switch at the same frequency as CLK.
Feedback output. FBOUT is dedicated for external feedback. It switches at the same frequency as CLK. When externally wired to
FBIN, FBOUT completes the feedback loop of the PLL.
Clock outputs. These outputs provide low-skew copies of CLK. Output bank Y(0:9) is enabled via the G input. These outputs can be
disabled to a logic-low state by de-asserting the G control input.
