fFault,HFXT Oscillator fault frequency(4)(3) 0 800 kHz
This represents all the parasitic capacitance present at the HFXIN and HFXOUT terminals, respectively, including parasitic bond and package capacitance. The effective load capacitance, CL,eff can be computed as CIN x COUT / (CIN + COUT), where CIN and COUT is the total capacitance at the HFXIN and HFXOUT terminals, respectively.
Requires external capacitors at both terminals. Values are specified by crystal manufacturers. Recommended values supported are 14 pF, 16 pF, and 18 pF. Maximum shunt capacitance of 7 pF. The PCB adds additional capacitance, so it must also be considered in the overall capacitance. Verify that the recommended effective load capacitance of the selected crystal is met.
Measured with logic-level input frequency but also applies to operation with crystals.
Frequencies above the MAX specification do not set the fault flag. Frequencies between the MIN and MAX might set the flag. A static condition or stuck at fault condition will set the flag.
To improve EMI on the HFXT oscillator the following guidelines should be observed.
  • Keep the traces 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 HFXIN and HFXOUT.
  • Avoid running PCB traces underneath or adjacent to the HFXIN and HFXOUT pins.
  • Use assembly materials and processes that avoid any parasitic load on the oscillator HFXIN and HFXOUT pins.
  • If conformal coating is used, ensure that it does not induce capacitive/resistive leakage between the oscillator pins.
When HFXTBYPASS is set, HFXT 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. Duty cycle requirements are defined by DCHFXT, SW.
Maximum frequency of operation of the entire device cannot be exceeded.
HFFREQ = \{0\} is not supported for HFXT crystal mode of operation.
Oscillation allowance is based on a safety factor of 5 for recommended crystals.
Includes start-up counter of 1024 clock cycles.
