High Performance Single-Chip 10/100 Non-PCI Ethernet Controller

Note 7.14 Frequency Deviation Over Time is also reffered to as Aging.

Datasheet

Note 7.15 The total deviation for the Transmitter Clock Frequency is specified by IEEE 802.3u as

+/- 50 PPM.

Note 7.16

This number includes the pad, the bond wire and the lead frame. PCB capacitance is not

included in this value. The XTAL1 and XTAL2 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.
