LMK01000ISQE/NOPB datasheet by Texas Instruments

LMK01000ISQE/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the LMK01000ISQE/NOPB to minimize noise and ensure optimal performance?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the clock signal traces as short as possible and away from other signals. Additionally, use a common mode filter or a ferrite bead to filter out high-frequency noise.
• How do I ensure the LMK01000ISQE/NOPB is properly bypassed for optimal performance?
  Use a 0.1uF ceramic capacitor and a 10uF electrolytic capacitor in parallel, placed as close as possible to the VCC pin. Ensure the capacitors are connected to a solid ground plane to minimize inductance.
• What is the maximum clock frequency that the LMK01000ISQE/NOPB can support?
  The LMK01000ISQE/NOPB can support clock frequencies up to 100 MHz, but the maximum frequency may vary depending on the specific application and PCB layout.
• How do I configure the LMK01000ISQE/NOPB for a specific clock output frequency?
  Use the TI Clock Design Tool or the LMK01000 evaluation module to configure the device for a specific clock output frequency. The tool will provide the necessary register settings and component values.
• What is the power consumption of the LMK01000ISQE/NOPB, and how can I minimize it?
  The power consumption of the LMK01000ISQE/NOPB is typically around 20mA at 3.3V. To minimize power consumption, use the lowest possible supply voltage, disable unused outputs, and use the power-down mode when not in use.
