Since CTLEs are passive filters, they''re no different in PAM4 systems than in PAM2-NRZ systems, but with four symbol levels, the decisions that PAM4 DFEs feedback are more complicated.

Note that proper comparison of PAM5 and PAM4 would require specific proposals for PAM5 implementation, but it is unlikely that such comparison will be more favorable to PAM5

PAM4 has the advantage of doubling the data rate with respect to the same electrical characteristics (UI, Nyquist frequency, symbol rate) of an NRZ/PAM2 signal, as shown in Fig.1-1.

PAM4 effectively doubles the data rate for a link bandwidth at the expense of reduced signal to noise ratio (SNR). PAM4 is used in 400GE, 800GE, and 1.6T Ethernet as well as PCIe 6.0® and other
