Serial data of I
Internal pull-up resistor 120K to Vdd
Serial clock of I
Internal pull-up resistor 120K to Vdd
True reference clock input, 3.3V tolerant input
True Feedback output, dedicated for external
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
internal PLL for synchronization with CLK_INT to
eliminate phase error.
