CDCM61004RHBR datasheet by Texas Instruments

CDCM61004RHBR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of CDCM61004RHBR?
  A good PCB layout for CDCM61004RHBR involves keeping the input and output traces short and symmetrical, using a solid ground plane, and placing decoupling capacitors close to the device. TI provides a recommended layout in the datasheet and application notes.
• How do I ensure the CDCM61004RHBR is properly powered and decoupled?
  Ensure a stable power supply with minimal noise and ripple. Use a 1-10uF decoupling capacitor between VCC and GND, and an additional 100nF capacitor between VCC and GND for high-frequency noise filtering. Place these capacitors close to the device.
• What is the maximum clock frequency that CDCM61004RHBR can handle?
  The CDCM61004RHBR can handle clock frequencies up to 1.5 GHz. However, the actual frequency limit may vary depending on the specific application, PCB layout, and signal integrity.
• How do I troubleshoot issues with CDCM61004RHBR, such as signal jitter or skew?
  Use an oscilloscope to measure the input and output signals, and check for signal integrity issues. Verify the PCB layout, power supply, and decoupling. Consult the datasheet and application notes for troubleshooting guidelines.
• Can I use CDCM61004RHBR in a non-50Ω system?
  While CDCM61004RHBR is optimized for 50Ω systems, it can be used in non-50Ω systems with proper impedance matching. Consult the datasheet and application notes for guidance on impedance matching and signal termination.
