CDCLVD2108RGZR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a symmetrical layout with matched trace lengths and impedance control to minimize jitter and noise. It's also essential to keep the clock input traces short and away from noisy signals. A good rule of thumb is to keep the clock traces within 1 inch of the device and use a solid ground plane underneath.
  • The CDCLVD2108RGZR outputs should be terminated with a 50-ohm resistor to VCC or GND, depending on the output signal type (LVDS or LVPECL). This termination helps to reduce signal reflections and ensures signal integrity. Additionally, it's recommended to use a series termination resistor (Rs) of 22-33 ohms to further reduce signal reflections.
  • The maximum clock frequency that can be input to the CDCLVD2108RGZR is 1.5 GHz. However, the device can generate output clock frequencies up to 3.2 GHz. It's essential to ensure that the input clock frequency is within the specified range to maintain device reliability and performance.
  • The CDCLVD2108RGZR can be configured using the SEL pins (SEL0-SEL3) to select the desired output clock frequency and format. The configuration is done by setting the SEL pins to the appropriate logic levels (high or low) according to the device's truth table. It's recommended to consult the datasheet and application notes for specific configuration details.
  • The power consumption of the CDCLVD2108RGZR depends on the output clock frequency, output format, and operating conditions. The typical power consumption is around 350 mW. To reduce power consumption, you can use the device's power-down mode (PD pin) to disable the output clocks when not in use. Additionally, using a lower output clock frequency and optimizing the output format can also help reduce power consumption.
