Frequency Synthesis & Clocks (PLL)

PLL products support frequency synthesis and clock functions in your system.

PLL Selection Considerations

Reference input
Frequency synthesis
Clock / frequency output
Conceptual function diagram only; not a device internal architecture or verified reference circuit. Confirm interface, direction and operating conditions for the selected model.
Target frequency
List the reference input and target output frequencies first, then check the frequency range of each specific model.
Frequency Division
Distinguish integer-N and fractional-N requirements and select according to the system frequency plan.
System Configuration
Confirm supply, interface and configuration conditions before determining system connections.
