Analog ground.
"Complementary" Feedback output, dedicated for external feedback. It
switches at the same frequency as the CLK. This output must be wired
to FB_INC.
"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.
"Complementary" Feedback input, provides signal to the internal PLL
for synchronization with CLK_INC to eliminate phase error.
Data input for I2C serial input, 5V tolerant input
