(1) Includes parasitic bond and package capacitance (approximately 2 pF per pin).
Because the PCB adds additional capacitance, verify the correct load by measuring the ACLK frequency. For a correct setup, the effective load capacitance should always match the specification of the used crystal.
(2) Requires external capacitors at both terminals. Values are specified by crystal manufacturers.
(3) Measured with logic-level input frequency but also applies to operation with crystals.
(4) Frequencies below the MIN specification set the fault flag. Frequencies above the MAX specification do not set the fault flag. Frequencies that are between MIN and MAX might set the flag.
(5) To improve EMI on the XT1 oscillator, the following guidelines should be observed.
  • Keep the trace between the device and the crystal as short as possible.
  • Design a good ground plane around the oscillator pins.
  • Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT.
  • Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins.
  • Use assembly materials and processes that avoid any parasitic load on the oscillator XIN and XOUT pins.
  • If conformal coating is used, make sure that it does not induce capacitive or resistive leakage between the oscillator pins.
(6) When XT1BYPASS is set, XT1 circuits are automatically powered down. Input signal is a digital square wave with parametrics defined in the Schmitt-Trigger Inputs section of this data sheet.
(7) Maximum frequency of operation of the entire device cannot be exceeded.
(8) Oscillation allowance is based on a safety factor of 5 for recommended crystals. The oscillation allowance is a function of the XT1DRIVEx settings and the effective load. In general, comparable oscillator allowance can be achieved based on the following guidelines, but should be evaluated based on the actual crystal selected for the application:
  • For XT1DRIVEx = 0, CL,eff ≤ 6 pF.
  • For XT1DRIVEx = 1, 6 pF ≤ CL,eff ≤ 9 pF.
  • For XT1DRIVEx = 2, 6 pF ≤ CL,eff ≤ 10 pF.
  • For XT1DRIVEx = 3, CL,eff ≥ 6 pF.
