3.3V Frequency select latched input pin with internal 120kohm pull down resistor.
3.3V Frequency select latched input pin with internal 120kohm pull down resistor.
This pin establishes the reference for the differential current-mode output pairs. It
requires a fixed precision resistor to ground. 475ohm is the standard value for
100ohm differential impedance. Other impedances require different values. See
data sheet.
Ground pin for the PLL core.
