"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.
Data input for I2C serial input, 5V tolerant input
