DSC1001BI1-019.6608 - Microchip

DSC1001BI1-019.6608 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DSC1001BI1-019.6608?
  The recommended power-up sequence is to apply VDD first, followed by VDDO, and then the clock signal. This ensures proper initialization and prevents potential latch-up conditions.
• How do I configure the DSC1001BI1-019.6608 for a specific frequency output?
  The DSC1001BI1-019.6608 can be configured for a specific frequency output by programming the internal registers using the I2C interface. The frequency is determined by the values written to the Frequency Control Register (FCR) and the Clock Divider Register (CDR). Refer to the datasheet for the specific register values and equations to calculate the desired frequency.
• What is the maximum clock frequency that the DSC1001BI1-019.6608 can generate?
  The maximum clock frequency that the DSC1001BI1-019.6608 can generate is 133.33 MHz. However, the actual maximum frequency may be limited by the specific application, PCB layout, and clock distribution network.
• Can the DSC1001BI1-019.6608 be used as a clock generator for PCIe applications?
  Yes, the DSC1001BI1-019.6608 can be used as a clock generator for PCIe applications. It meets the PCIe specification for clock jitter and frequency accuracy, making it a suitable solution for PCIe clock generation.
• How do I ensure the DSC1001BI1-019.6608 is properly terminated for optimal signal integrity?
  Proper termination is critical for optimal signal integrity. The DSC1001BI1-019.6608 requires a 50-ohm termination resistor on the clock output pin. Additionally, ensure that the PCB layout and clock distribution network are designed to minimize signal reflections and attenuation.
