46
IREF
OUT
This pin establishes the reference current for the differential current-mode output
pairs. This pin requires a fixed precision resistor tied to ground in order to establish
the appropriate current. 475 ohms is the standard value.
47
GNDA
PWR
Ground pin for the PLL core.
48
VDDA
PWR
3.3V power for the PLL core.
