Note 9-6

Frequency Deviation Over Time is also referred to as Aging.

Note 9-7

0 °C for commercial version, -40 °C for industrial and Grade 3 Automotive.

Note 9-8

+70 °C for commercial version, +85 °C for industrial and Grade 3 Automotive.

Note 9-9

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 calculate the value of the two external load capacitors. These two external load capacitors

determine the accuracy of the 25.000 MHz frequency.

9.7.2

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
