Description
Reference clock input
VCO frequency select. For choosing optimal VCO operating frequency depending on input frequency. HIGH is for higher
frequencies, LOW is for lower frequencies.
PLL feedback input which is connected to either a Q or a Q/2 output. External feedback provides flexibility for different output
frequency relationships. See the Frequency Selection Table for more information.
Clock outputs
Clock output. Matched in phase, but frequency is half the Q frequency.
Output enable/asynchronous reset. Resets all output registers. When 0, all outputs are held in a tri-stated condition. When 1,
outputs are enabled.
PLL enable. Enables and disables the PLL. Allows the SYNC input to be single-stepped for systemdebug.
Power supply for output buffers.
Power supply for phase lock loop and other internal circuitries.
Ground supply for output buffers.
Ground supply for phase lock loop and other internal circuitries.
