CDCLVD1204RGTR datasheet by Texas Instruments

CDCLVD1204RGTR Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the CDCLVD1204RGTR to minimize jitter and noise?
  Texas Instruments recommends a symmetrical layout with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, use a 50-ohm transmission line for the clock output and keep the power and ground pins as close as possible to the device.
• How do I ensure the CDCLVD1204RGTR is properly powered and decoupled?
  Use a low-ESR capacitor (e.g., 0.1 μF) between VCC and GND, and a 10 μF capacitor between VCC and GND for bulk decoupling. Ensure the power supply is stable and has low noise. Also, use a 1 kΩ resistor in series with the VCC pin to prevent voltage overshoot.
• What is the maximum frequency deviation allowed for the input clock signal?
  The CDCLVD1204RGTR can tolerate up to ±100 ppm frequency deviation for the input clock signal. However, it's recommended to keep the deviation as low as possible to ensure optimal performance.
• How do I configure the CDCLVD1204RGTR for a specific output frequency?
  Use the TI Clock Design Tool or the CDCLVD1204RGTR datasheet to determine the required RSET and RDIV values for the desired output frequency. The tool or datasheet will provide the recommended resistor values for the specific output frequency.
• What is the maximum output current for each output pin?
  The maximum output current for each output pin is 24 mA. Ensure that the output current does not exceed this value to prevent device damage or malfunction.
