# Pin Description
1 Digital Power (Input) - Positive power supply for the digital and analog sections.
2 Ground (Input) - Ground reference.
3 PLL Clock Output (Output) - PLL clock output.
4
Auxiliary Output (Output) - This pin outputs a buffered version of one of the input or output clocks,
or a status signal, depending on configuration.
5 Frequency Reference Clock Input (Input) - Clock input for the Digital PLL frequency reference.

Crystal Connections (XTI/XTO) / Timing Reference Clock Input (REF_CLK) (Input/Output) -
XTI/XTO are I/O pins for an external crystal which may be used to generate the low-jitter PLL input
clock. REF_CLK is an input for an externally generated low-jitter reference clock.
8 Mode Select (Input) - M2 is a configurable mode selection pin.
9 Mode Select (Input) - M1 is a configurable mode selection pin.
10 Mode Select (Input) - M0 is a configurable mode selection pin.
