DSC1123CI5-100.0000T - Microchip

DSC1123CI5-100.0000T Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DSC1123CI5-100.0000T?
  The recommended power-up sequence is to apply VDD first, followed by VDDO, and then the clock signal. This ensures proper initialization and prevents damage to the device.
• How do I configure the DSC1123CI5-100.0000T for a specific frequency output?
  The DSC1123CI5-100.0000T can be configured for a specific frequency output using the I2C interface. You need to write the desired frequency value to the corresponding registers (e.g., FREQ0, FREQ1, and FREQ2) and then update the configuration by writing to the CONTROL register.
• What is the maximum clock frequency that the DSC1123CI5-100.0000T can generate?
  The DSC1123CI5-100.0000T can generate clock frequencies up to 100 MHz. However, the maximum frequency may vary depending on the specific application, output load, and operating conditions.
• How do I ensure the DSC1123CI5-100.0000T is in a low-power state when not in use?
  To ensure the DSC1123CI5-100.0000T is in a low-power state when not in use, you can write to the CONTROL register to set the device in standby mode. Additionally, you can also disconnect the clock input or set the clock input to a low frequency to reduce power consumption.
• What is the typical startup time for the DSC1123CI5-100.0000T?
  The typical startup time for the DSC1123CI5-100.0000T is around 10 ms. However, this time may vary depending on the specific application, operating conditions, and clock frequency.
