Description
Reference clock input
Reference clock input
Reference clock select. When 1, selects SYNC
1
. When 0, selects SYNC
0
.
VCO frequency select. For choosing optimal VCO operating frequency depending on input frequency.
PLL feedback input which is connected to a user selected output pin. External feedback provides flexibility for different output frequency
relationships. See the Frequency Selection Table for more information.
Clock outputs
Clock output. Matched in frequency, but inverted with respect to Q.
Clock output. Matched in phase, but frequency is double the Q frequency.
Clock output. Matched in phase, but frequency is half the Q frequency.
PLL lock indication signal. 1 indicates positive lock. 0 indicates that the PLL is not locked and outputs may not be synchronized to the inputs.
Asynchronous reset. Resets all output registers. When 0, all outputs are held in a tri-stated condition. When 1, outputs are enabled (normal
operation).
PLL enable. When 1, PLL is enabled (normal operation). When 0, PLL is disabled (for testing purposes).
