This latched input selects the polarity of the OE pins.
0 = OE pins active high, 1 = OE pins active low (OE#)
0.7V differential complement clock output
0.7V differential true clock output
Active high input for enabling output 4.
0 = tri-state outputs, 1= enable outputs
Active high input for enabling output 7.
0 = tri-state outputs, 1= enable outputs
3.3V output indicating PLL Lock Status. This pin goes high when
lock is achieved.
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.
Ground pin for the PLL core.
3.3V power for the PLL core.
