DS12887+ Frequently Asked Questions (FAQ)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.

  • To ensure accurate clock output, make sure to use a high-quality crystal oscillator, and ensure that the load capacitance on the X1 and X2 pins is within the recommended range of 10pF to 20pF.

  • The maximum frequency deviation allowed for the DS12887+ is ±100 ppm over the operating temperature range of -40°C to +85°C.

  • Yes, the DS12887+ can be used in a system with multiple clock domains. However, ensure that the clock signals are properly synchronized and that the device is configured to handle the multiple clock domains correctly.

  • To troubleshoot issues with the DS12887+, start by checking the power supply voltages, clock signal quality, and crystal oscillator circuit. Also, verify that the device is properly configured and that the clock output is within the specified frequency range.
