PD
Feedback Clock Input. Connect to an output for normal operation.
Master Reset/Output Enable Input. When asserted high, resets
all of the internal flip-flops and also disables all of the outputs.
When pulled low, releases the internal flip-flops from reset and
enables all of the outputs.
PLL Enable Input. When asserted high, PLL is enabled. And
when set low, PLL is bypassed.
Reference Select Input. When high, TCLK is the reference clock
and when low, PECL clock is selected.
Frequency Select Inputs. See Frequency Table.
