(4)

Does not include programable start-up counter.

(5)

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 × COUT / (CIN + COUT), where CIN and COUT are the

total capacitance at the HFXIN and HFXOUT terminals, respectively.

(6)

Requires external capacitors at both terminals to meet the effective load capacitance specified by crystal manufacturers. Recommended

effective load capacitance 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.

(7)

Frequencies greater than the MAX specification do not set the fault flag. Frequencies between the MIN and MAX specification may set

the flag. A static condition or stuck-at-fault condition sets the fault flag.

(8)

Measured with logic-level input frequency but also applies to operation with crystals.
