CDCDB803RSLT Frequently Asked Questions (FAQs)

  • Texas Instruments recommends following a star topology for clock distribution, using a solid ground plane, and keeping clock traces short and shielded to minimize jitter and noise. Additionally, use a 50-ohm transmission line and terminate it with a 50-ohm resistor to match the impedance.
  • The CDCDB803RSLT can be configured using the TI Clock Design Tool or the TI Clock Architect tool. These tools allow you to select the desired clock frequency, output format, and other parameters to generate a configuration file that can be loaded into the device.
  • The CDCDB803RSLT can support clock frequencies up to 800 MHz, but the maximum frequency depends on the specific output format and the quality of the input clock signal.
  • The CDCDB803RSLT requires a 1.8V power supply, and it's recommended to use a low-dropout regulator (LDO) to ensure a clean and stable power supply. Additionally, decouple the power pins with 0.1uF and 10uF capacitors to filter out noise and reduce jitter.
  • Yes, the CDCDB803RSLT can be used in a redundant clocking system to provide a high-reliability clocking solution. The device has built-in features such as clock redundancy and automatic clock switching to ensure that the system remains operational even in the event of a clock failure.
