13

IN True reference clock input, 3.3V tolerant input

14, 32,36 NONE Not connected

True Feedback output, dedicated for external

33

OUT feedback. It switches at the same frequency as the

CLK. This output must be wired to FB_INT.

True Feedback input, provides feedback signal to the

35

IN internal PLL for synchronization with CLK_INT to

eliminate phase error.
