I
Clock Input. CLK provides the reference signal to the internal PLL.

I
Output Bank Enable. When 1G is high, all outputs 1Y(0:4) are enabled.
When 1G is low, Outputs 1Y(0:4) are disabled to a logic-low state.
Output Bank Enable. When 2G is high, all outputs 2Y(0:3) are enabled.
When 2G is low, Outputs 2Y(0:3) are disabled to a logic-low state.
Feedback Output. FBOUT completes the feedback loop of the PLL by being
wired to FBIN.

Clock Outputs. These outputs provide low-skew copies of CLKIN. Each output
has an embedded series-damping resistor.

Clock Outputs. These outputs provide low-skew copies of CLKIN. Each output
has an embedded series-damping resistor.
AV

Power
Analog Power Supply. AV
cc
provides the power reference for the analog
circuitry. AV
cc
can be also used to bypass the PLL for the test purpose.
When AV
cc
is strapped to ground, PLL is bypassed and CLK is buffered directly
to the device outputs.
