Clause 22.2.2.1 requires the MII TX_CLK to have an accuracy of ± 100 ppm.
Clause 24.2.3.4 is more stringent. It requires the code-bit timer to have an accuracy of 0.005% (that is, ±50 ppm).
ICS1893 Data Sheet - Release
Although the 10TCSR and 100TCSR pins do not need to be bypassed, include placeholders for
bypass capacitors on a printed circuit board that uses the ICS1893.
