Note 7: 0 °C for commercial version, -40 °C for industrial version.

Note 8: +70 °C for commercial version, +85 °C for industrial version.

Note 9: This number includes the pad, the bond wire and the lead frame. PCB capacitance is not included in this

value. The XTALI/CLK_IN pin, XTALO pin and PCB capacitance values are required to accurately calcu-

late the value of the two external load capacitors. These two external load capacitors determine the accu-

racy of the 25.000 MHz frequency.

10.7.2

EXTERNAL REFERENCE CLOCK (CLK_IN)

When using an external reference clock, the following input clock specifications are suggested:

•25 MHz

• 50% duty cycle ±10%, ±100 ppm

• Jitter < 100 ps RMS
