CDCM61004RHBT datasheet by Texas Instruments

CDCM61004RHBT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the CDCM61004RHBT?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane and a separate power plane for the clock distribution. The clock input and output traces should be routed as differential pairs, and the power and ground pins should be decoupled with 0.1uF capacitors.
• How do I ensure the CDCM61004RHBT is properly powered?
  The CDCM61004RHBT requires a 3.3V power supply, and it's recommended to use a low-dropout regulator (LDO) to ensure a clean power supply. Additionally, decoupling capacitors should be placed close to the power pins to filter out noise.
• What is the maximum clock frequency supported by the CDCM61004RHBT?
  The CDCM61004RHBT supports clock frequencies up to 100 MHz, but the maximum frequency may vary depending on the specific application and PCB layout. It's recommended to consult the datasheet and perform simulations to ensure the device can operate at the desired frequency.
• How do I configure the CDCM61004RHBT for a specific clock output frequency?
  The CDCM61004RHBT has a programmable clock divider that allows the output frequency to be set. The divider ratio can be set using the SEL0-SEL2 pins, and the output frequency can be calculated using the formula: Output Frequency = Input Frequency / (Divider Ratio + 1).
• What is the typical power consumption of the CDCM61004RHBT?
  The typical power consumption of the CDCM61004RHBT is around 20-30 mA, depending on the clock frequency and output load. However, this value can vary depending on the specific application and operating conditions.
