LTC6990CS6#TRPBF Frequently Asked Questions (FAQs)

• What is the maximum frequency of the clock input?
  The maximum frequency of the clock input is 50MHz, but it can be limited by the specific application and layout.
• How do I ensure the oscillator starts up reliably?
  To ensure the oscillator starts up reliably, make sure to decouple the power supply, use a high-quality clock source, and follow proper PCB layout guidelines.
• What is the recommended value for the feedback resistor (RFB) and capacitor (CFB)?
  The recommended value for RFB is 1kΩ to 10kΩ, and for CFB is 10pF to 100pF, but the optimal values depend on the specific application and frequency of operation.
• How do I minimize jitter in the output clock signal?
  To minimize jitter, use a high-quality clock source, minimize noise on the power supply, and use a low-jitter oscillator configuration, such as the 'Low Jitter' mode.
• Can I use the LTC6990CS6 as a voltage-controlled oscillator (VCO)?
  Yes, the LTC6990CS6 can be used as a VCO by applying a control voltage to the VCTRL pin, but the frequency range and linearity may vary depending on the specific application.
