CDCM9102RHBT datasheet by Texas Instruments

CDCM9102RHBT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the CDCM9102RHBT?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane and a separate power plane for the VCC and VDD pins. The clock input traces should be kept short and away from noisy signals.
• How do I ensure the CDCM9102RHBT is properly powered?
  The CDCM9102RHBT requires a 1.8V power supply for VCC and a 3.3V power supply for VDD. Ensure that the power supplies are clean and well-regulated, and that the voltage rails are properly decoupled with capacitors.
• What is the maximum clock frequency supported by the CDCM9102RHBT?
  The CDCM9102RHBT supports clock frequencies up to 200 MHz. However, the maximum frequency may be limited by the quality of the clock signal and the PCB layout.
• How do I configure the CDCM9102RHBT for a specific clock output frequency?
  The CDCM9102RHBT can be configured using the SEL0 and SEL1 pins to select one of four possible clock output frequencies. Consult the datasheet for the specific configuration options.
• What is the typical jitter performance of the CDCM9102RHBT?
  The CDCM9102RHBT has a typical jitter performance of 150 fs RMS for the clock output. However, this can vary depending on the quality of the input clock signal and the PCB layout.
